+ * the offset number of all inner tuples. If we encounter any invalid tuples
+ * with 0xfffe during insertion, we throw an error, though scans still handle
+ * them. You should only encounter invalid tuples if you pg_upgrade a pre-9.1
+ * gist index which already has invalid tuples in it because of a crash. That

+ * Heap tuple header.  To avoid wasting space, the fields should be

+ *
+ * Datums of composite types (row types) share the same general structure
+ * as on-disk tuples, so that the same routines can be used to build and
+ * examine them.  However the requirements are slightly different: a Datum
+ * does not need any transaction visibility information, and it does need
+ * a length word and some embedded type information.  We can achieve this
+ * by overlaying the xmin/cmin/xmax/cmax/xvac fields of a heap tuple
+ * with the fields needed in the Datum case.  Typically, all tuples built
+ * in-memory will be initialized with the Datum fields; but when a tuple is
+ * about to be inserted in a table, the transaction fields will be filled,
+ * overwriting the datum fields.
+ *
+ * The overall structure of a heap tuple looks like:
+ *			fixed fields (HeapTupleHeaderData struct)
+ *			nulls bitmap (if HEAP_HASNULL is set in t_infomask)
+ *			alignment padding (as needed to make user data MAXALIGN'd)
+ *			object ID (if HEAP_HASOID_OLD is set in t_infomask, not created
+ *          anymore)
+ *			user data fields
+ *
+ * We store five "virtual" fields Xmin, Cmin, Xmax, Cmax, and Xvac in three
+ * physical fields.  Xmin and Xmax are always really stored, but Cmin, Cmax
+ * and Xvac share a field.  This works because we know that Cmin and Cmax
+ * are only interesting for the lifetime of the inserting and deleting
+ * transaction respectively.  If a tuple is inserted and deleted in the same
+ * transaction, we store a "combo" command id that can be mapped to the real
+ * cmin and cmax, but only by use of local state within the originating
+ * backend.  See combocid.c for more details.  Meanwhile, Xvac is only set by
+ * old-style VACUUM FULL, which does not have any command sub-structure and so
+ * does not need either Cmin or Cmax.  (This requires that old-style VACUUM
+ * FULL never try to move a tuple whose Cmin or Cmax is still interesting,
+ * ie, an insert-in-progress or delete-in-progress tuple.)
+ *
+ * A word about t_ctid: whenever a new tuple is stored on disk, its t_ctid
+ * is initialized with its own TID (location).  If the tuple is ever updated,
+ * its t_ctid is changed to point to the replacement version of the tuple.  Or
+ * if the tuple is moved from one partition to another, due to an update of
+ * the partition key, t_ctid is set to a special value to indicate that
+ * (see ItemPointerSetMovedPartitions).  Thus, a tuple is the latest version
+ * of its row iff XMAX is invalid or
+ * t_ctid points to itself (in which case, if XMAX is valid, the tuple is
+ * either locked or deleted).  One can follow the chain of t_ctid links
+ * to find the newest version of the row, unless it was moved to a different
+ * partition.  Beware however that VACUUM might
+ * erase the pointed-to (newer) tuple before erasing the pointing (older)
+ * tuple.  Hence, when following a t_ctid link, it is necessary to check
+ * to see if the referenced slot is empty or contains an unrelated tuple.
+ * Check that the referenced tuple has XMIN equal to the referencing tuple's
+ * XMAX to verify that it is actually the descendant version and not an
+ * unrelated tuple stored into a slot recently freed by VACUUM.  If either
+ * check fails, one may assume that there is no live descendant version.
+ *
+ * t_ctid is sometimes used to store a speculative insertion token, instead
+ * of a real TID.  A speculative token is set on a tuple that's being
+ * inserted, until the inserter is sure that it wants to go ahead with the
+ * insertion.  Hence a token should only be seen on a tuple with an XMAX
+ * that's still in-progress, or invalid/aborted.  The token is replaced with
+ * the tuple's real TID when the insertion is confirmed.  One should never
+ * see a speculative insertion token while following a chain of t_ctid links,
+ * because they are not used on updates, only insertions.
+ *
+ * Following the fixed header fields, the nulls bitmap is stored (beginning
+ * at t_bits).  The bitmap is *not* stored if t_infomask shows that there
+ * are no nulls in the tuple.  If an OID field is present (as indicated by
+ * t_infomask), then it is stored just before the user data, which begins at
+ * the offset shown by t_hoff.  Note that t_hoff must be a multiple of
+ * MAXALIGN.

+ * Notes on B-Tree tuple format, and key and non-key attributes:
+ *
+ * INCLUDE B-Tree indexes have non-key attributes.  These are extra
+ * attributes that may be returned by index-only scans, but do not influence
+ * the order of items in the index (formally, non-key attributes are not
+ * considered to be part of the key space).  Non-key attributes are only
+ * present in leaf index tuples whose item pointers actually point to heap
+ * tuples (non-pivot tuples).  _bt_check_natts() enforces the rules
+ * described here.
+ *
+ * Non-pivot tuple format (plain/non-posting variant):
+ *
+ *  t_tid | t_info | key values | INCLUDE columns, if any
+ *
+ * t_tid points to the heap TID, which is a tiebreaker key column as of
+ * BTREE_VERSION 4.
+ *
+ * Non-pivot tuples complement pivot tuples, which only have key columns.
+ * The sole purpose of pivot tuples is to represent how the key space is
+ * separated.  In general, any B-Tree index that has more than one level
+ * (i.e. any index that does not just consist of a metapage and a single
+ * leaf root page) must have some number of pivot tuples, since pivot
+ * tuples are used for traversing the tree.  Suffix truncation can omit
+ * trailing key columns when a new pivot is formed, which makes minus
+ * infinity their logical value.  Since BTREE_VERSION 4 indexes treat heap
+ * TID as a trailing key column that ensures that all index tuples are
+ * physically unique, it is necessary to represent heap TID as a trailing
+ * key column in pivot tuples, though very often this can be truncated
+ * away, just like any other key column. (Actually, the heap TID is
+ * omitted rather than truncated, since its representation is different to
+ * the non-pivot representation.)
+ *
+ * Pivot tuple format:
+ *
+ *  t_tid | t_info | key values | [heap TID]
+ *
+ * We store the number of columns present inside pivot tuples by abusing
+ * their t_tid offset field, since pivot tuples never need to store a real
+ * offset (pivot tuples generally store a downlink in t_tid, though).  The
+ * offset field only stores the number of columns/attributes when the
+ * INDEX_ALT_TID_MASK bit is set, which doesn't count the trailing heap
+ * TID column sometimes stored in pivot tuples -- that's represented by
+ * the presence of BT_PIVOT_HEAP_TID_ATTR.  The INDEX_ALT_TID_MASK bit in
+ * t_info is always set on BTREE_VERSION 4 pivot tuples, since
+ * BTreeTupleIsPivot() must work reliably on heapkeyspace versions.
+ *
+ * In version 2 or version 3 (!heapkeyspace) indexes, INDEX_ALT_TID_MASK
+ * might not be set in pivot tuples.  BTreeTupleIsPivot() won't work
+ * reliably as a result.  The number of columns stored is implicitly the
+ * same as the number of columns in the index, just like any non-pivot
+ * tuple. (The number of columns stored should not vary, since suffix
+ * truncation of key columns is unsafe within any !heapkeyspace index.)
+ *
+ * The 12 least significant bits from t_tid's offset number are used to
+ * represent the number of key columns within a pivot tuple.  This leaves 4
+ * status bits (BT_STATUS_OFFSET_MASK bits), which are shared by all tuples
+ * that have the INDEX_ALT_TID_MASK bit set (set in t_info) to store basic
+ * tuple metadata.  BTreeTupleIsPivot() and BTreeTupleIsPosting() use the
+ * BT_STATUS_OFFSET_MASK bits.
+ *
+ * Sometimes non-pivot tuples also use a representation that repurposes
+ * t_tid to store metadata rather than a TID.  PostgreSQL v13 introduced a
+ * new non-pivot tuple format to support deduplication: posting list
+ * tuples.  Deduplication merges together multiple equal non-pivot tuples
+ * into a logically equivalent, space efficient representation.  A posting
+ * list is an array of ItemPointerData elements.  Non-pivot tuples are
+ * merged together to form posting list tuples lazily, at the point where
+ * we'd otherwise have to split a leaf page.
+ *
+ * Posting tuple format (alternative non-pivot tuple representation):
+ *
+ *  t_tid | t_info | key values | posting list (TID array)
+ *
+ * Posting list tuples are recognized as such by having the
+ * INDEX_ALT_TID_MASK status bit set in t_info and the BT_IS_POSTING status
+ * bit set in t_tid's offset number.  These flags redefine the content of
+ * the posting tuple's t_tid to store the location of the posting list
+ * (instead of a block number), as well as the total number of heap TIDs
+ * present in the tuple (instead of a real offset number).
+ *
+ * The 12 least significant bits from t_tid's offset number are used to
+ * represent the number of heap TIDs present in the tuple, leaving 4 status
+ * bits (the BT_STATUS_OFFSET_MASK bits).  Like any non-pivot tuple, the
+ * number of columns stored is always implicitly the total number in the
+ * index (in practice there can never be non-key columns stored, since
+ * deduplication is not supported with INCLUDE indexes).

+ * high key of the left/original page appears last of all (and must always be
+ * present).
+ *
+ * Page split records that need the REDO routine to deal with a posting list
+ * split directly will have an explicit newitem, which is actually an
+ * orignewitem (the newitem as it was before the posting list split, not
+ * after).  A posting list split always has a newitem that comes immediately

+ * splits with an _L variant page split record, and usually both the new
+ * posting list and the final newitem go on the left page (the existing

+ * indicates that the REDO routine must reconstruct a new posting list tuple
+ * that is needed for the left page.)
+ *
+ * This posting list split handling is equivalent to the xl_btree_insert REDO
+ * routine's INSERT_POST handling.  While the details are more complicated
+ * here, the concept and goals are exactly the same.  See _bt_swap_posting()
+ * for details on posting list splits.

+ *
+ * The right page's data portion contains the right page's tuples in the form

+ * variant.  The right page's tuples also include the right page's high key
+ * with either variant (moved from the left/original page during the split),
+ * unless the split happened to be of the rightmost page on its level, where
+ * there is no high key for new right page.

+ * A ScanKey represents the application of a comparison operator between
+ * a table or index column and a constant.  When it's part of an array of
+ * ScanKeys, the comparison conditions are implicitly ANDed.  The index
+ * column is the left argument of the operator, if it's a binary operator.
+ * (The data structure can support unary indexable operators too; in that
+ * case sk_argument would go unused.  This is not currently implemented.)
+ *
+ * For an index scan, sk_strategy and sk_subtype must be set correctly for
+ * the operator.  When using a ScanKey in a heap scan, these fields are not
+ * used and may be set to InvalidStrategy/InvalidOid.
+ *
+ * If the operator is collation-sensitive, sk_collation must be set
+ * correctly as well.
+ *
+ * A ScanKey can also represent a ScalarArrayOpExpr, that is a condition
+ * "column op ANY(ARRAY[...])".  This is signaled by the SK_SEARCHARRAY
+ * flag bit.  The sk_argument is not a value of the operator's right-hand
+ * argument type, but rather an array of such values, and the per-element
+ * comparisons are to be ORed together.
+ *
+ * A ScanKey can also represent a condition "column IS NULL" or "column
+ * IS NOT NULL"; these cases are signaled by the SK_SEARCHNULL and
+ * SK_SEARCHNOTNULL flag bits respectively.  The argument is always NULL,
+ * and the sk_strategy, sk_subtype, sk_collation, and sk_func fields are
+ * not used (unless set by the index AM).
+ *
+ * SK_SEARCHARRAY, SK_SEARCHNULL and SK_SEARCHNOTNULL are supported only
+ * for index scans, not heap scans; and not all index AMs support them,
+ * only those that set amsearcharray or amsearchnulls respectively.
+ *
+ * A ScanKey can also represent an ordering operator invocation, that is
+ * an ordering requirement "ORDER BY indexedcol op constant".  This looks
+ * the same as a comparison operator, except that the operator doesn't
+ * (usually) yield boolean.  We mark such ScanKeys with SK_ORDER_BY.
+ * SK_SEARCHARRAY, SK_SEARCHNULL, SK_SEARCHNOTNULL cannot be used here.
+ *
+ * Note: in some places, ScanKeys are used as a convenient representation
+ * for the invocation of an access method support procedure.  In this case
+ * sk_strategy/sk_subtype are not meaningful (but sk_collation can be); and
+ * sk_func may refer to a function that returns something other than boolean.

+ * about the status of individual table tuples.  These are conceptually one
+ * single array.  Using two arrays keeps the TM_IndexDelete struct small,
+ * which makes sorting the first array (the deltids array) fast.
+ *
+ * Some index AM callers perform simple index tuple deletion (by specifying
+ * bottomup = false), and include only known-dead deltids.  These known-dead
+ * entries are all marked knowndeletable = true directly (typically these are
+ * TIDs from LP_DEAD-marked index tuples), but that isn't strictly required.
+ *
+ * Callers that specify bottomup = true are "bottom-up index deletion"
+ * callers.  The considerations for the tableam are more subtle with these
+ * callers because they ask the tableam to perform highly speculative work,
+ * and might only expect the tableam to check a small fraction of all entries.
+ * Caller is not allowed to specify knowndeletable = true for any entry
+ * because everything is highly speculative.  Bottom-up caller provides
+ * context and hints to tableam -- see comments below for details on how index
+ * AMs and tableams should coordinate during bottom-up index deletion.
+ *
+ * Simple index deletion callers may ask the tableam to perform speculative
+ * work, too.  This is a little like bottom-up deletion, but not too much.
+ * The tableam will only perform speculative work when it's practically free
+ * to do so in passing for simple deletion caller (while always performing
+ * whatever work is needed to enable knowndeletable/LP_DEAD index tuples to
+ * be deleted within index AM).  This is the real reason why it's possible for
+ * simple index deletion caller to specify knowndeletable = false up front
+ * (this means "check if it's possible for me to delete corresponding index
+ * tuple when it's cheap to do so in passing").  The index AM should only
+ * include "extra" entries for index tuples whose TIDs point to a table block
+ * that tableam is expected to have to visit anyway (in the event of a block
+ * orientated tableam).  The tableam isn't strictly obligated to check these
+ * "extra" TIDs, but a block-based AM should always manage to do so in
+ * practice.
+ *
+ * The final contents of the deltids/status arrays are interesting to callers
+ * that ask tableam to perform speculative work (i.e. when _any_ items have
+ * knowndeletable set to false up front).  These index AM callers will
+ * naturally need to consult final state to determine which index tuples are
+ * in fact deletable.
+ *
+ * The index AM can keep track of which index tuple relates to which deltid by
+ * setting idxoffnum (and/or relying on each entry being uniquely identifiable
+ * using tid), which is important when the final contents of the array will
+ * need to be interpreted -- the array can shrink from initial size after
+ * tableam processing and/or have entries in a new order (tableam may sort
+ * deltids array for its own reasons).  Bottom-up callers may find that final
+ * ndeltids is 0 on return from call to tableam, in which case no index tuple
+ * deletions are possible.  Simple deletion callers can rely on any entries
+ * they know to be deletable appearing in the final array as deletable.

+ *		development purposes (such as in-progress patches and forks);
+ *		they should not appear in released versions.
+ *
+ *		OIDs 10000-11999 are reserved for assignment by genbki.pl, for use
+ *		when the .dat files in src/include/catalog/ do not specify an OID
+ *		for a catalog entry that requires one.  Note that genbki.pl assigns
+ *		these OIDs independently in each catalog, so they're not guaranteed
+ *		to be globally unique.  Furthermore, the bootstrap backend and
+ *		initdb's post-bootstrap processing can also assign OIDs in this range.
+ *		The normal OID-generation logic takes care of any OID conflicts that
+ *		might arise from that.
+ *
+ *		OIDs 12000-16383 are reserved for unpinned objects created by initdb's
+ *		post-bootstrap processing.  initdb forces the OID generator up to
+ *		12000 as soon as it's made the pinned objects it's responsible for.
+ *
+ *		OIDs beginning at 16384 are assigned from the OID generator
+ *		during normal multiuser operation.  (We force the generator up to
+ *		16384 as soon as we are in normal operation.)
+ *
+ * The choices of 8000, 10000 and 12000 are completely arbitrary, and can be
+ * moved if we run low on OIDs in any category.  Changing the macros below,
+ * and updating relevant documentation (see bki.sgml and RELEASE_CHANGES),
+ * should be sufficient to do this.  Moving the 16384 boundary between
+ * initdb-assigned OIDs and user-defined objects would be substantially
+ * more painful, however, since some user-defined OIDs will appear in
+ * on-disk data; such a change would probably break pg_upgrade.
+ *
+ * NOTE: if the OID generator wraps around, we skip over OIDs 0-16383
+ * and resume with 16384.  This minimizes the odds of OID conflict, by not
+ * reassigning OIDs that might have been assigned during initdb.  Critically,
+ * it also ensures that no user-created object will be considered pinned.

+ * IDENTIFICATION
+ *		src/include/access/xlogreader.h
+ *
+ * NOTES
+ *		See the definition of the XLogReaderState struct for instructions on
+ *		how to use the XLogReader infrastructure.
+ *
+ *		The basic idea is to allocate an XLogReaderState via
+ *		XLogReaderAllocate(), position the reader to the first record with
+ *		XLogBeginRead() or XLogFindNextRecord(), and call XLogReadRecord()
+ *		until it returns NULL.
+ *
+ *		Callers supply a page_read callback if they want to call
+ *		XLogReadRecord or XLogFindNextRecord; it can be passed in as NULL
+ *		otherwise.  The WALRead function can be used as a helper to write
+ *		page_read callbacks, but it is not mandatory; callers that use it,
+ *		must supply segment_open callbacks.  The segment_close callback
+ *		must always be supplied.
+ *
+ *		After reading a record with XLogReadRecord(), it's decomposed into
+ *		the per-block and main data parts, and the parts can be accessed
+ *		with the XLogRec* macros and functions. You can also decode a
+ *		record that's already constructed in memory, without reading from
+ *		disk, by calling the DecodeXLogRecord() function.

+ * "hole" is all zeros, we remove it from the stored data (and it's not counted
+ * in the XLOG record's CRC, either).  Hence, the amount of block data actually
+ * present is (BLCKSZ - <length of "hole" bytes>).
+ *
+ * Additionally, when wal_compression is enabled, we will try to compress full
+ * page images using one of the supported algorithms, after removing the
+ * "hole". This can reduce the WAL volume, but at some extra cost of CPU spent
+ * on the compression during WAL logging. In this case, since the "hole"
+ * length cannot be calculated by subtracting the number of page image bytes
+ * from BLCKSZ, basically it needs to be stored as an extra information.
+ * But when no "hole" exists, we can assume that the "hole" length is zero
+ * and no such an extra information needs to be stored. Note that
+ * the original version of page image is stored in WAL instead of the
+ * compressed one if the number of bytes saved by compression is less than
+ * the length of extra information. Hence, when a page image is successfully
+ * compressed, the amount of block data actually present is less than
+ * BLCKSZ - the length of "hole" bytes - the length of extra information.

+ *	  "Catalog version number" for PostgreSQL.
+ *
+ * The catalog version number is used to flag incompatible changes in
+ * the PostgreSQL system catalogs.  Whenever anyone changes the format of
+ * a system catalog relation, or adds, deletes, or modifies standard
+ * catalog entries in such a way that an updated backend wouldn't work
+ * with an old database (or vice versa), the catalog version number
+ * should be changed.  The version number stored in pg_control by initdb
+ * is checked against the version number compiled into the backend at
+ * startup time, so that a backend can refuse to run in an incompatible
+ * database.
+ *
+ * The point of this feature is to provide a finer grain of compatibility
+ * checking than is possible from looking at the major version number
+ * stored in PG_VERSION.  It shouldn't matter to end users, but during
+ * development cycles we usually make quite a few incompatible changes
+ * to the contents of the system catalogs, and we don't want to bump the
+ * major version number for each one.  What we can do instead is bump
+ * this internal version number.  This should save some grief for
+ * developers who might otherwise waste time tracking down "bugs" that
+ * are really just code-vs-database incompatibilities.
+ *
+ * The rule for developers is: if you commit a change that requires
+ * an initdb, you should update the catalog version number (as well as
+ * notifying the pgsql-hackers mailing list, which has been the
+ * informal practice for a long time).
+ *
+ * The catalog version number is placed here since modifying files in
+ * include/catalog is the most common kind of initdb-forcing change.
+ * But it could be used to protect any kind of incompatible change in
+ * database contents or layout, such as altering tuple headers.

+ * pg_amop.h
+ *	  definition of the "access method operator" system catalog (pg_amop)
+ *
+ * The amop table identifies the operators associated with each index operator
+ * family and operator class (classes are subsets of families).  An associated
+ * operator can be either a search operator or an ordering operator, as
+ * identified by amoppurpose.
+ *
+ * The primary key for this table is <amopfamily, amoplefttype, amoprighttype,
+ * amopstrategy>.  amoplefttype and amoprighttype are just copies of the
+ * operator's oprleft/oprright, ie its declared input data types.  The
+ * "default" operators for a particular opclass within the family are those
+ * with amoplefttype = amoprighttype = opclass's opcintype.  An opfamily may
+ * also contain other operators, typically cross-data-type operators.  All the
+ * operators within a family are supposed to be compatible, in a way that is
+ * defined by each individual index AM.
+ *
+ * We also keep a unique index on <amopopr, amoppurpose, amopfamily>, so that
+ * we can use a syscache to quickly answer questions of the form "is this
+ * operator in this opfamily, and if so what are its semantics with respect to
+ * the family?"  This implies that the same operator cannot be listed for
+ * multiple strategy numbers within a single opfamily, with the exception that
+ * it's possible to list it for both search and ordering purposes (with
+ * different strategy numbers for the two purposes).
+ *
+ * amopmethod is a copy of the owning opfamily's opfmethod field.  This is an
+ * intentional denormalization of the catalogs to buy lookup speed.

+ * Currently, objsubid is unused and zero for all other kinds of objects.

+ * pg_opclass.h
+ *	  definition of the "operator class" system catalog (pg_opclass)
+ *
+ * The primary key for this table is <opcmethod, opcname, opcnamespace> ---
+ * that is, there is a row for each valid combination of opclass name and
+ * index access method type.  This row specifies the expected input data type
+ * for the opclass (the type of the heap column, or the expression output type
+ * in the case of an index expression).  Note that types binary-coercible to
+ * the specified type will be accepted too.
+ *
+ * For a given <opcmethod, opcintype> pair, there can be at most one row that
+ * has opcdefault = true; this row is the default opclass for such data in
+ * such an index.  (This is not currently enforced by an index, because we
+ * don't support partial indexes on system catalogs.)
+ *
+ * Normally opckeytype = InvalidOid (zero), indicating that the data stored
+ * in the index is the same as the data in the indexed column.  If opckeytype
+ * is nonzero then it indicates that a conversion step is needed to produce
+ * the stored index data, which will be of type opckeytype (which might be
+ * the same or different from the input datatype).  Performing such a
+ * conversion is the responsibility of the index access method --- not all
+ * AMs support this.

+ *				hash-join hash table structures
+ *
+ * Each active hashjoin has a HashJoinTable control block, which is
+ * palloc'd in the executor's per-query context.  All other storage needed
+ * for the hashjoin is kept in private memory contexts, two for each hashjoin.
+ * This makes it easy and fast to release the storage when we don't need it
+ * anymore.  (Exception: data associated with the temp files lives in the
+ * per-query context too, since we always call buffile.c in that context.)
+ *
+ * The hashtable contexts are made children of the per-query context, ensuring
+ * that they will be discarded at end of statement even if the join is
+ * aborted early by an error.  (Likewise, any temporary files we make will
+ * be cleaned up by the virtual file manager in event of an error.)
+ *
+ * Storage that should live through the entire join is allocated from the
+ * "hashCxt", while storage that is only wanted for the current batch is
+ * allocated in the "batchCxt".  By resetting the batchCxt at the end of
+ * each batch, we free all the per-batch storage reliably and without tedium.
+ *
+ * During first scan of inner relation, we get its tuples from executor.
+ * If nbatch > 1 then tuples that don't belong in first batch get saved
+ * into inner-batch temp files. The same statements apply for the
+ * first scan of the outer relation, except we write tuples to outer-batch
+ * temp files.  After finishing the first scan, we do the following for
+ * each remaining batch:
+ *	1. Read tuples from inner batch file, load into hash buckets.
+ *	2. Read tuples from outer batch file, match to hash buckets and output.
+ *
+ * It is possible to increase nbatch on the fly if the in-memory hash table
+ * gets too big.  The hash-value-to-batch computation is arranged so that this
+ * can only cause a tuple to go into a later batch than previously thought,
+ * never into an earlier batch.  When we increase nbatch, we rescan the hash
+ * table and dump out any tuples that are now of a later batch to the correct
+ * inner batch file.  Subsequently, while reading either inner or outer batch
+ * files, we might find tuples that no longer belong to the current batch;
+ * if so, we just dump them out to the correct batch file.

+ * SPI plans have three states: saved, unsaved, or temporary.
+ *
+ * Ordinarily, the _SPI_plan struct itself as well as the argtypes array
+ * are in a dedicated memory context identified by plancxt (which can be
+ * really small).  All the other subsidiary state is in plancache entries
+ * identified by plancache_list (note: the list cells themselves are in
+ * plancxt).
+ *
+ * In an unsaved plan, the plancxt as well as the plancache entries' contexts
+ * are children of the SPI procedure context, so they'll all disappear at
+ * function exit.  plancache.c also knows that the plancache entries are
+ * "unsaved", so it doesn't link them into its global list; hence they do
+ * not respond to inval events.  This is OK since we are presumably holding
+ * adequate locks to prevent other backends from messing with the tables.
+ *
+ * For a saved plan, the plancxt is made a child of CacheMemoryContext
+ * since it should persist until explicitly destroyed.  Likewise, the
+ * plancache entries will be under CacheMemoryContext since we tell
+ * plancache.c to save them.  We rely on plancache.c to keep the cache
+ * entries up-to-date as needed in the face of invalidation events.
+ *
+ * There are also "temporary" SPI plans, in which the _SPI_plan struct is
+ * not even palloc'd but just exists in some function's local variable.
+ * The plancache entries are unsaved and exist under the SPI executor context,
+ * while additional data such as argtypes and list cells is loose in the SPI
+ * executor context.  Such plans can be identified by having plancxt == NULL.
+ *
+ * We can also have "one-shot" SPI plans (which are typically temporary,
+ * as described above).  These are meant to be executed once and discarded,
+ * and various optimizations are made on the assumption of single use.
+ * Note in particular that the CachedPlanSources within such an SPI plan
+ * are not "complete" until execution.
+ *
+ * Note: if the original query string contained only whitespace and comments,
+ * the plancache_list will be NIL and so there is no place to store the
+ * query string.  We don't care about that, but we do care about the
+ * argument type array, which is why it's seemingly-redundantly stored.

+/*----------
+ * The executor stores tuples in a "tuple table" which is a List of
+ * independent TupleTableSlots.
+ *
+ * There's various different types of tuple table slots, each being able to
+ * store different types of tuples. Additional types of slots can be added
+ * without modifying core code. The type of a slot is determined by the
+ * TupleTableSlotOps* passed to the slot creation routine. The builtin types
+ * of slots are
+ *
+ * 1. physical tuple in a disk buffer page (TTSOpsBufferHeapTuple)
+ * 2. physical tuple constructed in palloc'ed memory (TTSOpsHeapTuple)
+ * 3. "minimal" physical tuple constructed in palloc'ed memory
+ *    (TTSOpsMinimalTuple)
+ * 4. "virtual" tuple consisting of Datum/isnull arrays (TTSOpsVirtual)
+ *
+ *
+ * The first two cases are similar in that they both deal with "materialized"
+ * tuples, but resource management is different.  For a tuple in a disk page
+ * we need to hold a pin on the buffer until the TupleTableSlot's reference
+ * to the tuple is dropped; while for a palloc'd tuple we usually want the
+ * tuple pfree'd when the TupleTableSlot's reference is dropped.
+ *
+ * A "minimal" tuple is handled similarly to a palloc'd regular tuple.
+ * At present, minimal tuples never are stored in buffers, so there is no
+ * parallel to case 1.  Note that a minimal tuple has no "system columns".
+ * (Actually, it could have an OID, but we have no need to access the OID.)
+ *
+ * A "virtual" tuple is an optimization used to minimize physical data copying
+ * in a nest of plan nodes.  Until materialized pass-by-reference Datums in
+ * the slot point to storage that is not directly associated with the
+ * TupleTableSlot; generally they will point to part of a tuple stored in a
+ * lower plan node's output TupleTableSlot, or to a function result
+ * constructed in a plan node's per-tuple econtext.  It is the responsibility
+ * of the generating plan node to be sure these resources are not released for
+ * as long as the virtual tuple needs to be valid or is materialized.  Note
+ * also that a virtual tuple does not have any "system columns".
+ *
+ * The Datum/isnull arrays of a TupleTableSlot serve double duty.  For virtual
+ * slots they are the authoritative data.  For the other builtin slots,
+ * the arrays contain data extracted from the tuple.  (In this state, any
+ * pass-by-reference Datums point into the physical tuple.)  The extracted
+ * information is built "lazily", ie, only as needed.  This serves to avoid
+ * repeated extraction of data from the physical tuple.
+ *
+ * A TupleTableSlot can also be "empty", indicated by flag TTS_FLAG_EMPTY set
+ * in tts_flags, holding no valid data.  This is the only valid state for a
+ * freshly-created slot that has not yet had a tuple descriptor assigned to
+ * it.  In this state, TTS_SHOULDFREE should not be set in tts_flags, tts_tuple
+ * must be NULL and tts_nvalid zero.
+ *
+ * The tupleDescriptor is simply referenced, not copied, by the TupleTableSlot
+ * code.  The caller of ExecSetSlotDescriptor() is responsible for providing
+ * a descriptor that will live as long as the slot does.  (Typically, both
+ * slots and descriptors are in per-query memory and are freed by memory
+ * context deallocation at query end; so it's not worth providing any extra
+ * mechanism to do more.  However, the slot will increment the tupdesc
+ * reference count if a reference-counted tupdesc is supplied.)
+ *
+ * When TTS_SHOULDFREE is set in tts_flags, the physical tuple is "owned" by
+ * the slot and should be freed when the slot's reference to the tuple is
+ * dropped.
+ *
+ * tts_values/tts_isnull are allocated either when the slot is created (when
+ * the descriptor is provided), or when a descriptor is assigned to the slot;
+ * they are of length equal to the descriptor's natts.
+ *
+ * The TTS_FLAG_SLOW flag is saved state for
+ * slot_deform_heap_tuple, and should not be touched by any other code.

+ * psqlscan_int.h
+ *	  lexical scanner internal declarations
+ *
+ * This file declares the PsqlScanStateData structure used by psqlscan.l
+ * and shared by other lexers compatible with it, such as psqlscanslash.l.
+ *
+ * One difficult aspect of this code is that we need to work in multibyte
+ * encodings that are not ASCII-safe.  A "safe" encoding is one in which each
+ * byte of a multibyte character has the high bit set (it's >= 0x80).  Since
+ * all our lexing rules treat all high-bit-set characters alike, we don't
+ * really need to care whether such a byte is part of a sequence or not.
+ * In an "unsafe" encoding, we still expect the first byte of a multibyte
+ * sequence to be >= 0x80, but later bytes might not be.  If we scan such
+ * a sequence as-is, the lexing rules could easily be fooled into matching
+ * such bytes to ordinary ASCII characters.  Our solution for this is to
+ * substitute 0xFF for each non-first byte within the data presented to flex.
+ * The flex rules will then pass the FF's through unmolested.  The
+ * psqlscan_emit() subroutine is responsible for looking back to the original
+ * string and replacing FF's with the corresponding original bytes.
+ *
+ * Another interesting thing we do here is scan different parts of the same
+ * input with physically separate flex lexers (ie, lexers written in separate
+ * .l files).  We can get away with this because the only part of the
+ * persistent state of a flex lexer that depends on its parsing rule tables
+ * is the start state number, which is easy enough to manage --- usually,
+ * in fact, we just need to set it to INITIAL when changing lexers.  But to
+ * make that work at all, we must use re-entrant lexers, so that all the
+ * relevant state is in the yyscan_t attached to the PsqlScanState;
+ * if we were using lexers with separate static state we would soon end up
+ * with dangling buffer pointers in one or the other.  Also note that this
+ * is unlikely to work very nicely if the lexers aren't all built with the
+ * same flex version, or if they don't use the same flex options.

+ *
+ * Note: we use our own routines on platforms that don't HAVE_STRUCT_ADDRINFO,

+ * policy is needed because on some platforms a manually installed libbind.a
+ * may provide getaddrinfo(), yet the system headers may not provide the
+ * struct definitions needed to call it.  To avoid conflict with the libbind
+ * definition in such cases, we rename our routines to pg_xxx() via macros.
+ *
+ * This code will also work on platforms where struct addrinfo is defined
+ * in the system headers but no getaddrinfo() can be located.

+ *
+ * ilist.h
+ *		integrated/inline doubly- and singly-linked lists
+ *
+ * These list types are useful when there are only a predetermined set of
+ * lists that an object could be in.  List links are embedded directly into
+ * the objects, and thus no extra memory management overhead is required.
+ * (Of course, if only a small proportion of existing objects are in a list,
+ * the link fields in the remainder would be wasted space.  But usually,
+ * it saves space to not have separately-allocated list nodes.)
+ *
+ * None of the functions here allocate any memory; they just manipulate
+ * externally managed memory.  The APIs for singly and doubly linked lists
+ * are identical as far as capabilities of both allow.
+ *
+ * Each list has a list header, which exists even when the list is empty.
+ * An empty singly-linked list has a NULL pointer in its header.
+ * There are two kinds of empty doubly linked lists: those that have been
+ * initialized to NULL, and those that have been initialized to circularity.
+ * (If a dlist is modified and then all its elements are deleted, it will be
+ * in the circular state.)	We prefer circular dlists because there are some
+ * operations that can be done without branches (and thus faster) on lists
+ * that use circular representation.  However, it is often convenient to
+ * initialize list headers to zeroes rather than setting them up with an
+ * explicit initialization function, so we also allow the other case.
+ *
+ * EXAMPLES
+ *
+ * Here's a simple example demonstrating how this can be used.  Let's assume
+ * we want to store information about the tables contained in a database.
+ *
+ * #include "lib/ilist.h"
+ *
+ * // Define struct for the databases including a list header that will be
+ * // used to access the nodes in the table list later on.
+ * typedef struct my_database
+ * {
+ *		char	   *datname;
+ *		dlist_head	tables;
+ *		// ...
+ * } my_database;
+ *
+ * // Define struct for the tables.  Note the list_node element which stores
+ * // prev/next list links.  The list_node element need not be first.
+ * typedef struct my_table
+ * {
+ *		char	   *tablename;
+ *		dlist_node	list_node;
+ *		perm_t		permissions;
+ *		// ...
+ * } my_table;
+ *
+ * // create a database
+ * my_database *db = create_database();
+ *
+ * // and add a few tables to its table list
+ * dlist_push_head(&db->tables, &create_table(db, "a")->list_node);
+ * ...
+ * dlist_push_head(&db->tables, &create_table(db, "b")->list_node);
+ *
+ *
+ * To iterate over the table list, we allocate an iterator variable and use
+ * a specialized looping construct.  Inside a dlist_foreach, the iterator's
+ * 'cur' field can be used to access the current element.  iter.cur points to
+ * a 'dlist_node', but most of the time what we want is the actual table
+ * information; dlist_container() gives us that, like so:
+ *
+ * dlist_iter	iter;
+ * dlist_foreach(iter, &db->tables)
+ * {
+ *		my_table   *tbl = dlist_container(my_table, list_node, iter.cur);
+ *		printf("we have a table: %s in database %s\n",
+ *			   tbl->tablename, db->datname);
+ * }
+ *
+ *
+ * While a simple iteration is useful, we sometimes also want to manipulate
+ * the list while iterating.  There is a different iterator element and looping
+ * construct for that.  Suppose we want to delete tables that meet a certain
+ * criterion:
+ *
+ * dlist_mutable_iter miter;
+ * dlist_foreach_modify(miter, &db->tables)
+ * {
+ *		my_table   *tbl = dlist_container(my_table, list_node, miter.cur);
+ *
+ *		if (!tbl->to_be_deleted)
+ *			continue;		// don't touch this one
+ *
+ *		// unlink the current table from the linked list
+ *		dlist_delete(miter.cur);
+ *		// as these lists never manage memory, we can still access the table
+ *		// after it's been unlinked
+ *		drop_table(db, tbl);
+ * }

+/*
+ * simplehash.h
+ *
+ *	  When included this file generates a "templated" (by way of macros)
+ *	  open-addressing hash table implementation specialized to user-defined
+ *	  types.
+ *
+ *	  It's probably not worthwhile to generate such a specialized implementation
+ *	  for hash tables that aren't performance or space sensitive.
+ *
+ *	  Compared to dynahash, simplehash has the following benefits:
+ *
+ *	  - Due to the "templated" code generation has known structure sizes and no
+ *	    indirect function calls (which show up substantially in dynahash
+ *	    profiles). These features considerably increase speed for small
+ *	    entries.
+ *	  - Open addressing has better CPU cache behavior than dynahash's chained
+ *	    hashtables.
+ *	  - The generated interface is type-safe and easier to use than dynahash,
+ *	    though at the cost of more complex setup.
+ *	  - Allocates memory in a MemoryContext or another allocator with a
+ *	    malloc/free style interface (which isn't easily usable in a shared
+ *	    memory context)
+ *	  - Does not require the overhead of a separate memory context.
+ *
+ * Usage notes:
+ *
+ *	  To generate a hash-table and associated functions for a use case several
+ *	  macros have to be #define'ed before this file is included.  Including
+ *	  the file #undef's all those, so a new hash table can be generated
+ *	  afterwards.
+ *	  The relevant parameters are:
+ *	  - SH_PREFIX - prefix for all symbol names generated. A prefix of 'foo'
+ *		will result in hash table type 'foo_hash' and functions like
+ *		'foo_insert'/'foo_lookup' and so forth.
+ *	  - SH_ELEMENT_TYPE - type of the contained elements
+ *	  - SH_KEY_TYPE - type of the hashtable's key
+ *	  - SH_DECLARE - if defined function prototypes and type declarations are
+ *		generated
+ *	  - SH_DEFINE - if defined function definitions are generated
+ *	  - SH_SCOPE - in which scope (e.g. extern, static inline) do function
+ *		declarations reside
+ *	  - SH_RAW_ALLOCATOR - if defined, memory contexts are not used; instead,
+ *	    use this to allocate bytes. The allocator must zero the returned space.
+ *	  - SH_USE_NONDEFAULT_ALLOCATOR - if defined no element allocator functions
+ *		are defined, so you can supply your own
+ *	  The following parameters are only relevant when SH_DEFINE is defined:
+ *	  - SH_KEY - name of the element in SH_ELEMENT_TYPE containing the hash key
+ *	  - SH_EQUAL(table, a, b) - compare two table keys
+ *	  - SH_HASH_KEY(table, key) - generate hash for the key
+ *	  - SH_STORE_HASH - if defined the hash is stored in the elements
+ *	  - SH_GET_HASH(tb, a) - return the field to store the hash in
+ *
+ *	  The element type is required to contain a "status" member that can store
+ *	  the range of values defined in the SH_STATUS enum.
+ *
+ *	  While SH_STORE_HASH (and subsequently SH_GET_HASH) are optional, because
+ *	  the hash table implementation needs to compare hashes to move elements
+ *	  (particularly when growing the hash), it's preferable, if possible, to
+ *	  store the element's hash in the element's data type. If the hash is so
+ *	  stored, the hash table will also compare hashes before calling SH_EQUAL
+ *	  when comparing two keys.
+ *
+ *	  For convenience the hash table create functions accept a void pointer
+ *	  that will be stored in the hash table type's member private_data. This
+ *	  allows callbacks to reference caller provided data.
+ *
+ *	  For examples of usage look at tidbitmap.c (file local definition) and
+ *	  execnodes.h/execGrouping.c (exposed declaration, file local
+ *	  implementation).
+ *
+ * Hash table design:
+ *
+ *	  The hash table design chosen is a variant of linear open-addressing. The
+ *	  reason for doing so is that linear addressing is CPU cache & pipeline
+ *	  friendly. The biggest disadvantage of simple linear addressing schemes
+ *	  are highly variable lookup times due to clustering, and deletions
+ *	  leaving a lot of tombstones around.  To address these issues a variant
+ *	  of "robin hood" hashing is employed.  Robin hood hashing optimizes
+ *	  chaining lengths by moving elements close to their optimal bucket
+ *	  ("rich" elements), out of the way if a to-be-inserted element is further
+ *	  away from its optimal position (i.e. it's "poor").  While that can make
+ *	  insertions slower, the average lookup performance is a lot better, and
+ *	  higher fill factors can be used in a still performant manner.  To avoid
+ *	  tombstones - which normally solve the issue that a deleted node's
+ *	  presence is relevant to determine whether a lookup needs to continue
+ *	  looking or is done - buckets following a deleted element are shifted
+ *	  backwards, unless they're empty or already at their optimal position.

+ *	  A template for a sort algorithm that supports varying degrees of
+ *	  specialization.

+ * Copyright (c) 2021-2022, PostgreSQL Global Development Group
+ * Portions Copyright (c) 1992-1994, Regents of the University of California
+ *
+ * Usage notes:
+ *
+ *	  To generate functions specialized for a type, the following parameter
+ *	  macros should be #define'd before this file is included.
+ *
+ *	  - ST_SORT - the name of a sort function to be generated
+ *	  - ST_ELEMENT_TYPE - type of the referenced elements
+ *	  - ST_DECLARE - if defined the functions and types are declared
+ *	  - ST_DEFINE - if defined the functions and types are defined
+ *	  - ST_SCOPE - scope (e.g. extern, static inline) for functions
+ *	  - ST_CHECK_FOR_INTERRUPTS - if defined the sort is interruptible
+ *
+ *	  Instead of ST_ELEMENT_TYPE, ST_ELEMENT_TYPE_VOID can be defined.  Then
+ *	  the generated functions will automatically gain an "element_size"
+ *	  parameter.  This allows us to generate a traditional qsort function.
+ *
+ *	  One of the following macros must be defined, to show how to compare
+ *	  elements.  The first two options are arbitrary expressions depending
+ *	  on whether an extra pass-through argument is desired, and the third
+ *	  option should be defined if the sort function should receive a
+ *	  function pointer at runtime.
+ *
+ *	  - ST_COMPARE(a, b) - a simple comparison expression
+ *	  - ST_COMPARE(a, b, arg) - variant that takes an extra argument
+ *	  - ST_COMPARE_RUNTIME_POINTER - sort function takes a function pointer
+ *
+ *	  To say that the comparator and therefore also sort function should
+ *	  receive an extra pass-through argument, specify the type of the
+ *	  argument.
+ *
+ *	  - ST_COMPARE_ARG_TYPE - type of extra argument
+ *
+ *	  The prototype of the generated sort function is:
+ *
+ *	  void ST_SORT(ST_ELEMENT_TYPE *data, size_t n,
+ *				   [size_t element_size,]
+ *				   [ST_SORT_compare_function compare,]
+ *				   [ST_COMPARE_ARG_TYPE *arg]);
+ *
+ *	  ST_SORT_compare_function is a function pointer of the following type:
+ *
+ *	  int (*)(const ST_ELEMENT_TYPE *a, const ST_ELEMENT_TYPE *b,
+ *			  [ST_COMPARE_ARG_TYPE *arg])
+ *
+ * HISTORY
+ *
+ *	  Modifications from vanilla NetBSD source:
+ *	  - Add do ... while() macro fix
+ *	  - Remove __inline, _DIAGASSERTs, __P
+ *	  - Remove ill-considered "swap_cnt" switch to insertion sort, in favor
+ *		of a simple check for presorted input.
+ *	  - Take care to recurse on the smaller partition, to bound stack usage
+ *	  - Convert into a header that can generate specialized functions

+ * MULE Internal Encoding (MIC)
+ *
+ * This encoding follows the design used within XEmacs; it is meant to
+ * subsume many externally-defined character sets.  Each character includes
+ * identification of the character set it belongs to, so the encoding is
+ * general but somewhat bulky.
+ *
+ * Currently PostgreSQL supports 5 types of MULE character sets:
+ *
+ * 1) 1-byte ASCII characters.  Each byte is below 0x80.
+ *
+ * 2) "Official" single byte charsets such as ISO-8859-1 (Latin1).
+ *	  Each MULE character consists of 2 bytes: LC1 + C1, where LC1 is
+ *	  an identifier for the charset (in the range 0x81 to 0x8d) and C1
+ *	  is the character code (in the range 0xa0 to 0xff).
+ *
+ * 3) "Private" single byte charsets such as SISHENG.  Each MULE
+ *	  character consists of 3 bytes: LCPRV1 + LC12 + C1, where LCPRV1
+ *	  is a private-charset flag, LC12 is an identifier for the charset,
+ *	  and C1 is the character code (in the range 0xa0 to 0xff).
+ *	  LCPRV1 is either 0x9a (if LC12 is in the range 0xa0 to 0xdf)
+ *	  or 0x9b (if LC12 is in the range 0xe0 to 0xef).
+ *
+ * 4) "Official" multibyte charsets such as JIS X0208.  Each MULE
+ *	  character consists of 3 bytes: LC2 + C1 + C2, where LC2 is
+ *	  an identifier for the charset (in the range 0x90 to 0x99) and C1
+ *	  and C2 form the character code (each in the range 0xa0 to 0xff).
+ *
+ * 5) "Private" multibyte charsets such as CNS 11643-1992 Plane 3.
+ *	  Each MULE character consists of 4 bytes: LCPRV2 + LC22 + C1 + C2,
+ *	  where LCPRV2 is a private-charset flag, LC22 is an identifier for
+ *	  the charset, and C1 and C2 form the character code (each in the range
+ *	  0xa0 to 0xff).  LCPRV2 is either 0x9c (if LC22 is in the range 0xf0
+ *	  to 0xf4) or 0x9d (if LC22 is in the range 0xf5 to 0xfe).
+ *
+ * "Official" encodings are those that have been assigned code numbers by
+ * the XEmacs project; "private" encodings have Postgres-specific charset
+ * identifiers.
+ *
+ * See the "XEmacs Internals Manual", available at http://www.xemacs.org,
+ * for more details.  Note that for historical reasons, Postgres'
+ * private-charset flag values do not match what XEmacs says they should be,
+ * so this isn't really exactly MULE (not that private charsets would be
+ * interoperable anyway).
+ *
+ * Note that XEmacs's implementation is different from what emacs does.
+ * We follow emacs's implementation, rather than XEmacs's.

+/*****************************************************************************
+ *	  System interrupt and critical section handling
+ *
+ * There are two types of interrupts that a running backend needs to accept
+ * without messing up its state: QueryCancel (SIGINT) and ProcDie (SIGTERM).
+ * In both cases, we need to be able to clean up the current transaction
+ * gracefully, so we can't respond to the interrupt instantaneously ---
+ * there's no guarantee that internal data structures would be self-consistent
+ * if the code is interrupted at an arbitrary instant.  Instead, the signal
+ * handlers set flags that are checked periodically during execution.
+ *
+ * The CHECK_FOR_INTERRUPTS() macro is called at strategically located spots
+ * where it is normally safe to accept a cancel or die interrupt.  In some
+ * cases, we invoke CHECK_FOR_INTERRUPTS() inside low-level subroutines that
+ * might sometimes be called in contexts that do *not* want to allow a cancel
+ * or die interrupt.  The HOLD_INTERRUPTS() and RESUME_INTERRUPTS() macros
+ * allow code to ensure that no cancel or die interrupt will be accepted,
+ * even if CHECK_FOR_INTERRUPTS() gets called in a subroutine.  The interrupt
+ * will be held off until CHECK_FOR_INTERRUPTS() is done outside any
+ * HOLD_INTERRUPTS() ... RESUME_INTERRUPTS() section.
+ *
+ * There is also a mechanism to prevent query cancel interrupts, while still
+ * allowing die interrupts: HOLD_CANCEL_INTERRUPTS() and
+ * RESUME_CANCEL_INTERRUPTS().
+ *
+ * Note that ProcessInterrupts() has also acquired a number of tasks that
+ * do not necessarily cause a query-cancel-or-die response.  Hence, it's
+ * possible that it will just clear InterruptPending and return.
+ *
+ * INTERRUPTS_PENDING_CONDITION() can be checked to see whether an
+ * interrupt needs to be serviced, without trying to do so immediately.
+ * Some callers are also interested in INTERRUPTS_CAN_BE_PROCESSED(),
+ * which tells whether ProcessInterrupts is sure to clear the interrupt.
+ *
+ * Special mechanisms are used to let an interrupt be accepted when we are
+ * waiting for a lock or when we are waiting for command input (but, of
+ * course, only if the interrupt holdoff counter is zero).  See the
+ * related code for details.
+ *
+ * A lost connection is handled similarly, although the loss of connection
+ * does not raise a signal, but is detected when we fail to write to the
+ * socket. If there was a signal for a broken connection, we could make use of
+ * it by setting ClientConnectionLost in the signal handler.
+ *
+ * A related, but conceptually distinct, mechanism is the "critical section"
+ * mechanism.  A critical section not only holds off cancel/die interrupts,
+ * but causes any ereport(ERROR) or ereport(FATAL) to become ereport(PANIC)
+ * --- that is, a system-wide reset is forced.  Needless to say, only really
+ * *critical* code should be marked as a critical section!	Currently, this
+ * mechanism is only used for XLOG-related code.

+ * "initialization," and NormalProcessing or "normal."
+ *
+ * The first two processing modes are used during special times. When the
+ * system state indicates bootstrap processing, transactions are all given
+ * transaction id "one" and are consequently guaranteed to commit. This mode
+ * is used during the initial generation of template databases.
+ *
+ * Initialization mode: used while starting a backend, until all normal
+ * initialization is complete.  Some code behaves differently when executed
+ * in this mode to enable system bootstrapping.
+ *

+ *	  ParamListInfo
+ *
+ *	  ParamListInfo structures are used to pass parameters into the executor
+ *	  for parameterized plans.  We support two basic approaches to supplying
+ *	  parameter values, the "static" way and the "dynamic" way.
+ *
+ *	  In the static approach, per-parameter data is stored in an array of
+ *	  ParamExternData structs appended to the ParamListInfo struct.
+ *	  Each entry in the array defines the value to be substituted for a
+ *	  PARAM_EXTERN parameter.  The "paramid" of a PARAM_EXTERN Param
+ *	  can range from 1 to numParams.
+ *
+ *	  Although parameter numbers are normally consecutive, we allow
+ *	  ptype == InvalidOid to signal an unused array entry.
+ *
+ *	  pflags is a flags field.  Currently the only used bit is:
+ *	  PARAM_FLAG_CONST signals the planner that it may treat this parameter
+ *	  as a constant (i.e., generate a plan that works only for this value
+ *	  of the parameter).
+ *
+ *	  In the dynamic approach, all access to parameter values is done through
+ *	  hook functions found in the ParamListInfo struct.  In this case,
+ *	  the ParamExternData array is typically unused and not allocated;
+ *	  but the legal range of paramid is still 1 to numParams.
+ *
+ *	  Although the data structure is really an array, not a list, we keep
+ *	  the old typedef name to avoid unnecessary code changes.
+ *
+ *	  There are 3 hook functions that can be associated with a ParamListInfo
+ *	  structure:
+ *
+ *	  If paramFetch isn't null, it is called to fetch the ParamExternData
+ *	  for a particular param ID, rather than accessing the relevant element
+ *	  of the ParamExternData array.  This supports the case where the array
+ *	  isn't there at all, as well as cases where the data in the array
+ *	  might be obsolete or lazily evaluated.  paramFetch must return the
+ *	  address of a ParamExternData struct describing the specified param ID;
+ *	  the convention above about ptype == InvalidOid signaling an invalid
+ *	  param ID still applies.  The returned struct can either be placed in
+ *	  the "workspace" supplied by the caller, or it can be in storage
+ *	  controlled by the paramFetch hook if that's more convenient.
+ *	  (In either case, the struct is not expected to be long-lived.)
+ *	  If "speculative" is true, the paramFetch hook should not risk errors
+ *	  in trying to fetch the parameter value, and should report an invalid
+ *	  parameter instead.
+ *
+ *	  If paramCompile isn't null, then it controls what execExpr.c compiles
+ *	  for PARAM_EXTERN Param nodes --- typically, this hook would emit a
+ *	  EEOP_PARAM_CALLBACK step.  This allows unnecessary work to be
+ *	  optimized away in compiled expressions.
+ *
+ *	  If parserSetup isn't null, then it is called to re-instantiate the
+ *	  original parsing hooks when a query needs to be re-parsed/planned.
+ *	  This is especially useful if the types of parameters might change
+ *	  from time to time, since it can replace the need to supply a fixed
+ *	  list of parameter types to the parser.
+ *
+ *	  Notice that the paramFetch and paramCompile hooks are actually passed
+ *	  the ParamListInfo struct's address; they can therefore access all
+ *	  three of the "arg" fields, and the distinction between paramFetchArg
+ *	  and paramCompileArg is rather arbitrary.

+ *	Nodes for a Query tree
+ ****************************************************************************/
+
+/*--------------------
+ * RangeTblEntry -
+ *	  A range table is a List of RangeTblEntry nodes.
+ *
+ *	  A range table entry may represent a plain relation, a sub-select in
+ *	  FROM, or the result of a JOIN clause.  (Only explicit JOIN syntax
+ *	  produces an RTE, not the implicit join resulting from multiple FROM
+ *	  items.  This is because we only need the RTE to deal with SQL features
+ *	  like outer joins and join-output-column aliasing.)  Other special
+ *	  RTE types also exist, as indicated by RTEKind.
+ *
+ *	  Note that we consider RTE_RELATION to cover anything that has a pg_class
+ *	  entry.  relkind distinguishes the sub-cases.
+ *
+ *	  alias is an Alias node representing the AS alias-clause attached to the
+ *	  FROM expression, or NULL if no clause.
+ *
+ *	  eref is the table reference name and column reference names (either
+ *	  real or aliases).  Note that system columns (OID etc) are not included
+ *	  in the column list.
+ *	  eref->aliasname is required to be present, and should generally be used
+ *	  to identify the RTE for error messages etc.
+ *
+ *	  In RELATION RTEs, the colnames in both alias and eref are indexed by
+ *	  physical attribute number; this means there must be colname entries for
+ *	  dropped columns.  When building an RTE we insert empty strings ("") for
+ *	  dropped columns.  Note however that a stored rule may have nonempty
+ *	  colnames for columns dropped since the rule was created (and for that
+ *	  matter the colnames might be out of date due to column renamings).
+ *	  The same comments apply to FUNCTION RTEs when a function's return type
+ *	  is a named composite type.
+ *
+ *	  In JOIN RTEs, the colnames in both alias and eref are one-to-one with
+ *	  joinaliasvars entries.  A JOIN RTE will omit columns of its inputs when
+ *	  those columns are known to be dropped at parse time.  Again, however,
+ *	  a stored rule might contain entries for columns dropped since the rule
+ *	  was created.  (This is only possible for columns not actually referenced
+ *	  in the rule.)  When loading a stored rule, we replace the joinaliasvars
+ *	  items for any such columns with null pointers.  (We can't simply delete
+ *	  them from the joinaliasvars list, because that would affect the attnums
+ *	  of Vars referencing the rest of the list.)
+ *
+ *	  inh is true for relation references that should be expanded to include
+ *	  inheritance children, if the rel has any.  This *must* be false for
+ *	  RTEs other than RTE_RELATION entries.
+ *
+ *	  inFromCl marks those range variables that are listed in the FROM clause.
+ *	  It's false for RTEs that are added to a query behind the scenes, such
+ *	  as the NEW and OLD variables for a rule, or the subqueries of a UNION.
+ *	  This flag is not used during parsing (except in transformLockingClause,
+ *	  q.v.); the parser now uses a separate "namespace" data structure to
+ *	  control visibility.  But it is needed by ruleutils.c to determine
+ *	  whether RTEs should be shown in decompiled queries.
+ *
+ *	  requiredPerms and checkAsUser specify run-time access permissions
+ *	  checks to be performed at query startup.  The user must have *all*
+ *	  of the permissions that are OR'd together in requiredPerms (zero
+ *	  indicates no permissions checking).  If checkAsUser is not zero,
+ *	  then do the permissions checks using the access rights of that user,
+ *	  not the current effective user ID.  (This allows rules to act as
+ *	  setuid gateways.)  Permissions checks only apply to RELATION RTEs.
+ *
+ *	  For SELECT/INSERT/UPDATE permissions, if the user doesn't have
+ *	  table-wide permissions then it is sufficient to have the permissions
+ *	  on all columns identified in selectedCols (for SELECT) and/or
+ *	  insertedCols and/or updatedCols (INSERT with ON CONFLICT DO UPDATE may
+ *	  have all 3).  selectedCols, insertedCols and updatedCols are bitmapsets,
+ *	  which cannot have negative integer members, so we subtract
+ *	  FirstLowInvalidHeapAttributeNumber from column numbers before storing
+ *	  them in these fields.  A whole-row Var reference is represented by
+ *	  setting the bit for InvalidAttrNumber.
+ *
+ *	  updatedCols is also used in some other places, for example, to determine
+ *	  which triggers to fire and in FDWs to know which changed columns they
+ *	  need to ship off.
+ *
+ *	  extraUpdatedCols is no longer used or maintained; it's always empty.
+ *
+ *	  securityQuals is a list of security barrier quals (boolean expressions),
+ *	  to be tested in the listed order before returning a row from the
+ *	  relation.  It is always NIL in parser output.  Entries are added by the
+ *	  rewriter to implement security-barrier views and/or row-level security.
+ *	  Note that the planner turns each boolean expression into an implicitly
+ *	  AND'ed sublist, as is its usual habit with qualification expressions.

+ * In an ORDER BY item, all fields must be valid.  (The eqop isn't essential
+ * here, but it's cheap to get it along with the sortop, and requiring it
+ * to be valid eases comparisons to grouping items.)  Note that this isn't
+ * actually enough information to determine an ordering: if the sortop is
+ * collation-sensitive, a collation OID is needed too.  We don't store the
+ * collation in SortGroupClause because it's not available at the time the
+ * parser builds the SortGroupClause; instead, consult the exposed collation
+ * of the referenced targetlist expression to find out what it is.
+ *
+ * In a grouping item, eqop must be valid.  If the eqop is a btree equality
+ * operator, then sortop should be set to a compatible ordering operator.
+ * We prefer to set eqop/sortop/nulls_first to match any ORDER BY item that
+ * the query presents for the same tlist item.  If there is none, we just
+ * use the default ordering op for the datatype.
+ *
+ * If the tlist item's type has a hash opclass but no btree opclass, then
+ * we will set eqop to the hash equality operator, sortop to InvalidOid,
+ * and nulls_first to false.  A grouping item of this kind can only be
+ * implemented by hashing, and of course it'll never match an ORDER BY item.
+ *
+ * The hashable flag is provided since we generally have the requisite
+ * information readily available when the SortGroupClause is constructed,
+ * and it's relatively expensive to get it again later.  Note there is no
+ * need for a "sortable" flag since OidIsValid(sortop) serves the purpose.
+ *
+ * A query might have both ORDER BY and DISTINCT (or DISTINCT ON) clauses.
+ * In SELECT DISTINCT, the distinctClause list is as long or longer than the
+ * sortClause list, while in SELECT DISTINCT ON it's typically shorter.
+ * The two lists must match up to the end of the shorter one --- the parser
+ * rearranges the distinctClause if necessary to make this true.  (This
+ * restriction ensures that only one sort step is needed to both satisfy the
+ * ORDER BY and set up for the Unique step.  This is semantically necessary
+ * for DISTINCT ON, and presents no real drawback for DISTINCT.)

+ * GroupingSet -
+ *		representation of CUBE, ROLLUP and GROUPING SETS clauses
+ *
+ * In a Query with grouping sets, the groupClause contains a flat list of
+ * SortGroupClause nodes for each distinct expression used.  The actual
+ * structure of the GROUP BY clause is given by the groupingSets tree.
+ *
+ * In the raw parser output, GroupingSet nodes (of all types except SIMPLE
+ * which is not used) are potentially mixed in with the expressions in the
+ * groupClause of the SelectStmt.  (An expression can't contain a GroupingSet,
+ * but a list may mix GroupingSet and expression nodes.)  At this stage, the
+ * content of each node is a list of expressions, some of which may be RowExprs
+ * which represent sublists rather than actual row constructors, and nested
+ * GroupingSet nodes where legal in the grammar.  The structure directly
+ * reflects the query syntax.
+ *
+ * In parse analysis, the transformed expressions are used to build the tlist
+ * and groupClause list (of SortGroupClause nodes), and the groupingSets tree
+ * is eventually reduced to a fixed format:
+ *
+ * EMPTY nodes represent (), and obviously have no content
+ *
+ * SIMPLE nodes represent a list of one or more expressions to be treated as an
+ * atom by the enclosing structure; the content is an integer list of
+ * ressortgroupref values (see SortGroupClause)
+ *
+ * CUBE and ROLLUP nodes contain a list of one or more SIMPLE nodes.
+ *
+ * SETS nodes contain a list of EMPTY, SIMPLE, CUBE or ROLLUP nodes, but after
+ * parse analysis they cannot contain more SETS nodes; enough of the syntactic
+ * transforms of the spec have been applied that we no longer have arbitrarily
+ * deep nesting (though we still preserve the use of cube/rollup).
+ *
+ * Note that if the groupingSets tree contains no SIMPLE nodes (only EMPTY
+ * nodes at the leaves), then the groupClause will be empty, but this is still
+ * an aggregation query (similar to using aggs or HAVING without GROUP BY).
+ *
+ * As an example, the following clause:
+ *
+ * GROUP BY GROUPING SETS ((a,b), CUBE(c,(d,e)))
+ *
+ * looks like this after raw parsing:
+ *
+ * SETS( RowExpr(a,b) , CUBE( c, RowExpr(d,e) ) )

+/*----------
+ * RelOptInfo
+ *		Per-relation information for planning/optimization
+ *
+ * For planning purposes, a "base rel" is either a plain relation (a table)
+ * or the output of a sub-SELECT or function that appears in the range table.
+ * In either case it is uniquely identified by an RT index.  A "joinrel"
+ * is the joining of two or more base rels.  A joinrel is identified by
+ * the set of RT indexes for its component baserels.  We create RelOptInfo
+ * nodes for each baserel and joinrel, and store them in the PlannerInfo's
+ * simple_rel_array and join_rel_list respectively.
+ *
+ * Note that there is only one joinrel for any given set of component
+ * baserels, no matter what order we assemble them in; so an unordered
+ * set is the right datatype to identify it with.
+ *
+ * We also have "other rels", which are like base rels in that they refer to
+ * single RT indexes; but they are not part of the join tree, and are given
+ * a different RelOptKind to identify them.
+ * Currently the only kind of otherrels are those made for member relations
+ * of an "append relation", that is an inheritance set or UNION ALL subquery.
+ * An append relation has a parent RTE that is a base rel, which represents
+ * the entire append relation.  The member RTEs are otherrels.  The parent
+ * is present in the query join tree but the members are not.  The member
+ * RTEs and otherrels are used to plan the scans of the individual tables or
+ * subqueries of the append set; then the parent baserel is given Append
+ * and/or MergeAppend paths comprising the best paths for the individual
+ * member rels.  (See comments for AppendRelInfo for more information.)
+ *
+ * At one time we also made otherrels to represent join RTEs, for use in
+ * handling join alias Vars.  Currently this is not needed because all join
+ * alias Vars are expanded to non-aliased form during preprocess_expression.
+ *
+ * We also have relations representing joins between child relations of
+ * different partitioned tables. These relations are not added to
+ * join_rel_level lists as they are not joined directly by the dynamic
+ * programming algorithm.
+ *
+ * There is also a RelOptKind for "upper" relations, which are RelOptInfos
+ * that describe post-scan/join processing steps, such as aggregation.
+ * Many of the fields in these RelOptInfos are meaningless, but their Path
+ * fields always hold Paths showing ways to do that processing step.
+ *
+ * Lastly, there is a RelOptKind for "dead" relations, which are base rels
+ * that we have proven we don't need to join after all.
+ *
+ * Parts of this data structure are specific to various scan and join
+ * mechanisms.  It didn't seem worth creating new node types for them.
+ *
+ *		relids - Set of base-relation identifiers; it is a base relation
+ *				if there is just one, a join relation if more than one
+ *		rows - estimated number of tuples in the relation after restriction
+ *			   clauses have been applied (ie, output rows of a plan for it)
+ *		consider_startup - true if there is any value in keeping plain paths for
+ *						   this rel on the basis of having cheap startup cost
+ *		consider_param_startup - the same for parameterized paths
+ *		reltarget - Default Path output tlist for this rel; normally contains
+ *					Var and PlaceHolderVar nodes for the values we need to
+ *					output from this relation.
+ *					List is in no particular order, but all rels of an
+ *					appendrel set must use corresponding orders.
+ *					NOTE: in an appendrel child relation, may contain
+ *					arbitrary expressions pulled up from a subquery!
+ *		pathlist - List of Path nodes, one for each potentially useful
+ *				   method of generating the relation
+ *		ppilist - ParamPathInfo nodes for parameterized Paths, if any
+ *		cheapest_startup_path - the pathlist member with lowest startup cost
+ *			(regardless of ordering) among the unparameterized paths;
+ *			or NULL if there is no unparameterized path
+ *		cheapest_total_path - the pathlist member with lowest total cost
+ *			(regardless of ordering) among the unparameterized paths;
+ *			or if there is no unparameterized path, the path with lowest
+ *			total cost among the paths with minimum parameterization
+ *		cheapest_unique_path - for caching cheapest path to produce unique
+ *			(no duplicates) output from relation; NULL if not yet requested
+ *		cheapest_parameterized_paths - best paths for their parameterizations;
+ *			always includes cheapest_total_path, even if that's unparameterized
+ *		direct_lateral_relids - rels this rel has direct LATERAL references to
+ *		lateral_relids - required outer rels for LATERAL, as a Relids set
+ *			(includes both direct and indirect lateral references)
+ *
+ * If the relation is a base relation it will have these fields set:
+ *
+ *		relid - RTE index (this is redundant with the relids field, but
+ *				is provided for convenience of access)
+ *		rtekind - copy of RTE's rtekind field
+ *		min_attr, max_attr - range of valid AttrNumbers for rel
+ *		attr_needed - array of bitmapsets indicating the highest joinrel
+ *				in which each attribute is needed; if bit 0 is set then
+ *				the attribute is needed as part of final targetlist
+ *		attr_widths - cache space for per-attribute width estimates;
+ *					  zero means not computed yet
+ *		lateral_vars - lateral cross-references of rel, if any (list of
+ *					   Vars and PlaceHolderVars)
+ *		lateral_referencers - relids of rels that reference this one laterally
+ *				(includes both direct and indirect lateral references)
+ *		indexlist - list of IndexOptInfo nodes for relation's indexes
+ *					(always NIL if it's not a table)
+ *		pages - number of disk pages in relation (zero if not a table)
+ *		tuples - number of tuples in relation (not considering restrictions)
+ *		allvisfrac - fraction of disk pages that are marked all-visible
+ *		eclass_indexes - EquivalenceClasses that mention this rel (filled
+ *						 only after EC merging is complete)
+ *		subroot - PlannerInfo for subquery (NULL if it's not a subquery)
+ *		subplan_params - list of PlannerParamItems to be passed to subquery
+ *
+ *		Note: for a subquery, tuples and subroot are not set immediately
+ *		upon creation of the RelOptInfo object; they are filled in when
+ *		set_subquery_pathlist processes the object.
+ *
+ *		For otherrels that are appendrel members, these fields are filled
+ *		in just as for a baserel, except we don't bother with lateral_vars.
+ *
+ * If the relation is either a foreign table or a join of foreign tables that
+ * all belong to the same foreign server and are assigned to the same user to
+ * check access permissions as (cf checkAsUser), these fields will be set:
+ *
+ *		serverid - OID of foreign server, if foreign table (else InvalidOid)
+ *		userid - OID of user to check access as (InvalidOid means current user)
+ *		useridiscurrent - we've assumed that userid equals current user
+ *		fdwroutine - function hooks for FDW, if foreign table (else NULL)
+ *		fdw_private - private state for FDW, if foreign table (else NULL)
+ *
+ * Two fields are used to cache knowledge acquired during the join search
+ * about whether this rel is provably unique when being joined to given other
+ * relation(s), ie, it can have at most one row matching any given row from
+ * that join relation.  Currently we only attempt such proofs, and thus only
+ * populate these fields, for base rels; but someday they might be used for
+ * join rels too:
+ *
+ *		unique_for_rels - list of Relid sets, each one being a set of other
+ *					rels for which this one has been proven unique
+ *		non_unique_for_rels - list of Relid sets, each one being a set of
+ *					other rels for which we have tried and failed to prove
+ *					this one unique
+ *
+ * The presence of the following fields depends on the restrictions
+ * and joins that the relation participates in:
+ *
+ *		baserestrictinfo - List of RestrictInfo nodes, containing info about
+ *					each non-join qualification clause in which this relation
+ *					participates (only used for base rels)
+ *		baserestrictcost - Estimated cost of evaluating the baserestrictinfo
+ *					clauses at a single tuple (only used for base rels)
+ *		baserestrict_min_security - Smallest security_level found among
+ *					clauses in baserestrictinfo
+ *		joininfo  - List of RestrictInfo nodes, containing info about each
+ *					join clause in which this relation participates (but
+ *					note this excludes clauses that might be derivable from
+ *					EquivalenceClasses)
+ *		has_eclass_joins - flag that EquivalenceClass joins are possible
+ *
+ * Note: Keeping a restrictinfo list in the RelOptInfo is useful only for
+ * base rels, because for a join rel the set of clauses that are treated as
+ * restrict clauses varies depending on which sub-relations we choose to join.
+ * (For example, in a 3-base-rel join, a clause relating rels 1 and 2 must be
+ * treated as a restrictclause if we join {1} and {2 3} to make {1 2 3}; but
+ * if we join {1 2} and {3} then that clause will be a restrictclause in {1 2}
+ * and should not be processed again at the level of {1 2 3}.)	Therefore,
+ * the restrictinfo list in the join case appears in individual JoinPaths
+ * (field joinrestrictinfo), not in the parent relation.  But it's OK for
+ * the RelOptInfo to store the joininfo list, because that is the same
+ * for a given rel no matter how we form it.
+ *
+ * We store baserestrictcost in the RelOptInfo (for base relations) because
+ * we know we will need it at least once (to price the sequential scan)
+ * and may need it multiple times to price index scans.
+ *
+ * A join relation is considered to be partitioned if it is formed from a
+ * join of two relations that are partitioned, have matching partitioning
+ * schemes, and are joined on an equijoin of the partitioning columns.
+ * Under those conditions we can consider the join relation to be partitioned
+ * by either relation's partitioning keys, though some care is needed if
+ * either relation can be forced to null by outer-joining.  For example, an
+ * outer join like (A LEFT JOIN B ON A.a = B.b) may produce rows with B.b
+ * NULL.  These rows may not fit the partitioning conditions imposed on B.
+ * Hence, strictly speaking, the join is not partitioned by B.b and thus
+ * partition keys of an outer join should include partition key expressions
+ * from the non-nullable side only.  However, if a subsequent join uses
+ * strict comparison operators (and all commonly-used equijoin operators are
+ * strict), the presence of nulls doesn't cause a problem: such rows couldn't
+ * match anything on the other side and thus they don't create a need to do
+ * any cross-partition sub-joins.  Hence we can treat such values as still
+ * partitioning the join output for the purpose of additional partitionwise
+ * joining, so long as a strict join operator is used by the next join.
+ *
+ * If the relation is partitioned, these fields will be set:
+ *
+ *		part_scheme - Partitioning scheme of the relation
+ *		nparts - Number of partitions
+ *		boundinfo - Partition bounds
+ *		partbounds_merged - true if partition bounds are merged ones
+ *		partition_qual - Partition constraint if not the root
+ *		part_rels - RelOptInfos for each partition
+ *		all_partrels - Relids set of all partition relids
+ *		partexprs, nullable_partexprs - Partition key expressions
+ *
+ * The partexprs and nullable_partexprs arrays each contain
+ * part_scheme->partnatts elements.  Each of the elements is a list of
+ * partition key expressions.  For partitioned base relations, there is one
+ * expression in each partexprs element, and nullable_partexprs is empty.
+ * For partitioned join relations, each base relation within the join
+ * contributes one partition key expression per partitioning column;
+ * that expression goes in the partexprs[i] list if the base relation
+ * is not nullable by this join or any lower outer join, or in the
+ * nullable_partexprs[i] list if the base relation is nullable.
+ * Furthermore, FULL JOINs add extra nullable_partexprs expressions
+ * corresponding to COALESCE expressions of the left and right join columns,
+ * to simplify matching join clauses to those lists.

+ * Restriction clause info.

+ * We create one of these for each AND sub-clause of a restriction condition

+ * ANDed, we can use any one of them or any subset of them to filter out
+ * tuples, without having to evaluate the rest.  The RestrictInfo node itself
+ * stores data used by the optimizer while choosing the best query plan.
+ *
+ * If a restriction clause references a single base relation, it will appear
+ * in the baserestrictinfo list of the RelOptInfo for that base rel.
+ *
+ * If a restriction clause references more than one base rel, it will
+ * appear in the joininfo list of every RelOptInfo that describes a strict
+ * subset of the base rels mentioned in the clause.  The joininfo lists are
+ * used to drive join tree building by selecting plausible join candidates.
+ * The clause cannot actually be applied until we have built a join rel
+ * containing all the base rels it references, however.
+ *
+ * When we construct a join rel that includes all the base rels referenced
+ * in a multi-relation restriction clause, we place that clause into the
+ * joinrestrictinfo lists of paths for the join rel, if neither left nor
+ * right sub-path includes all base rels referenced in the clause.  The clause
+ * will be applied at that join level, and will not propagate any further up
+ * the join tree.  (Note: the "predicate migration" code was once intended to
+ * push restriction clauses up and down the plan tree based on evaluation
+ * costs, but it's dead code and is unlikely to be resurrected in the
+ * foreseeable future.)
+ *
+ * Note that in the presence of more than two rels, a multi-rel restriction
+ * might reach different heights in the join tree depending on the join
+ * sequence we use.  So, these clauses cannot be associated directly with
+ * the join RelOptInfo, but must be kept track of on a per-join-path basis.
+ *
+ * RestrictInfos that represent equivalence conditions (i.e., mergejoinable
+ * equalities that are not outerjoin-delayed) are handled a bit differently.
+ * Initially we attach them to the EquivalenceClasses that are derived from
+ * them.  When we construct a scan or join path, we look through all the
+ * EquivalenceClasses and generate derived RestrictInfos representing the
+ * minimal set of conditions that need to be checked for this particular scan
+ * or join to enforce that all members of each EquivalenceClass are in fact
+ * equal in all rows emitted by the scan or join.
+ *
+ * When dealing with outer joins we have to be very careful about pushing qual
+ * clauses up and down the tree.  An outer join's own JOIN/ON conditions must
+ * be evaluated exactly at that join node, unless they are "degenerate"
+ * conditions that reference only Vars from the nullable side of the join.
+ * Quals appearing in WHERE or in a JOIN above the outer join cannot be pushed
+ * down below the outer join, if they reference any nullable Vars.
+ * RestrictInfo nodes contain a flag to indicate whether a qual has been
+ * pushed down to a lower level than its original syntactic placement in the
+ * join tree would suggest.  If an outer join prevents us from pushing a qual
+ * down to its "natural" semantic level (the level associated with just the
+ * base rels used in the qual) then we mark the qual with a "required_relids"
+ * value including more than just the base rels it actually uses.  By
+ * pretending that the qual references all the rels required to form the outer
+ * join, we prevent it from being evaluated below the outer join's joinrel.
+ * When we do form the outer join's joinrel, we still need to distinguish
+ * those quals that are actually in that join's JOIN/ON condition from those
+ * that appeared elsewhere in the tree and were pushed down to the join rel
+ * because they used no other rels.  That's what the is_pushed_down flag is
+ * for; it tells us that a qual is not an OUTER JOIN qual for the set of base
+ * rels listed in required_relids.  A clause that originally came from WHERE
+ * or an INNER JOIN condition will *always* have its is_pushed_down flag set.
+ * It's possible for an OUTER JOIN clause to be marked is_pushed_down too,
+ * if we decide that it can be pushed down into the nullable side of the join.
+ * In that case it acts as a plain filter qual for wherever it gets evaluated.
+ * (In short, is_pushed_down is only false for non-degenerate outer join
+ * conditions.  Possibly we should rename it to reflect that meaning?  But
+ * see also the comments for RINFO_IS_PUSHED_DOWN, below.)
+ *
+ * RestrictInfo nodes also contain an outerjoin_delayed flag, which is true
+ * if the clause's applicability must be delayed due to any outer joins
+ * appearing below it (ie, it has to be postponed to some join level higher
+ * than the set of relations it actually references).
+ *
+ * There is also an outer_relids field, which is NULL except for outer join
+ * clauses; for those, it is the set of relids on the outer side of the
+ * clause's outer join.  (These are rels that the clause cannot be applied to
+ * in parameterized scans, since pushing it into the join's outer side would
+ * lead to wrong answers.)
+ *
+ * There is also a nullable_relids field, which is the set of rels the clause
+ * references that can be forced null by some outer join below the clause.
+ *
+ * outerjoin_delayed = true is subtly different from nullable_relids != NULL:
+ * a clause might reference some nullable rels and yet not be
+ * outerjoin_delayed because it also references all the other rels of the
+ * outer join(s). A clause that is not outerjoin_delayed can be enforced
+ * anywhere it is computable.
+ *
+ * To handle security-barrier conditions efficiently, we mark RestrictInfo
+ * nodes with a security_level field, in which higher values identify clauses
+ * coming from less-trusted sources.  The exact semantics are that a clause
+ * cannot be evaluated before another clause with a lower security_level value
+ * unless the first clause is leakproof.  As with outer-join clauses, this
+ * creates a reason for clauses to sometimes need to be evaluated higher in
+ * the join tree than their contents would suggest; and even at a single plan
+ * node, this rule constrains the order of application of clauses.
+ *
+ * In general, the referenced clause might be arbitrarily complex.  The
+ * kinds of clauses we can handle as indexscan quals, mergejoin clauses,
+ * or hashjoin clauses are limited (e.g., no volatile functions).  The code
+ * for each kind of path is responsible for identifying the restrict clauses
+ * it can use and ignoring the rest.  Clauses not implemented by an indexscan,
+ * mergejoin, or hashjoin will be placed in the plan qual or joinqual field
+ * of the finished Plan node, where they will be enforced by general-purpose
+ * qual-expression-evaluation code.  (But we are still entitled to count
+ * their selectivity when estimating the result tuple count, if we
+ * can guess what it is...)
+ *
+ * When the referenced clause is an OR clause, we generate a modified copy
+ * in which additional RestrictInfo nodes are inserted below the top-level
+ * OR/AND structure.  This is a convenience for OR indexscan processing:
+ * indexquals taken from either the top level or an OR subclause will have
+ * associated RestrictInfo nodes.
+ *
+ * The can_join flag is set true if the clause looks potentially useful as
+ * a merge or hash join clause, that is if it is a binary opclause with
+ * nonoverlapping sets of relids referenced in the left and right sides.
+ * (Whether the operator is actually merge or hash joinable isn't checked,
+ * however.)

+ *
+ * It is not valid for either min_lefthand or min_righthand to be empty sets;
+ * if they were, this would break the logic that enforces join order.

+ * For a semijoin, we also extract the join operators and their RHS arguments
+ * and set semi_operators, semi_rhs_exprs, semi_can_btree, and semi_can_hash.
+ * This is done in support of possibly unique-ifying the RHS, so we don't

+ *
+ * For purposes of join selectivity estimation, we create transient

+ *
+ * pg_list.h
+ *	  interface for PostgreSQL generic list package
+ *
+ * Once upon a time, parts of Postgres were written in Lisp and used real
+ * cons-cell lists for major data structures.  When that code was rewritten
+ * in C, we initially had a faithful emulation of cons-cell lists, which
+ * unsurprisingly was a performance bottleneck.  A couple of major rewrites
+ * later, these data structures are actually simple expansible arrays;
+ * but the "List" name and a lot of the notation survives.
+ *
+ * One important concession to the original implementation is that an empty
+ * list is always represented by a null pointer (preferentially written NIL).
+ * Non-empty lists have a header, which will not be relocated as long as the
+ * list remains non-empty, and an expansible data array.
+ *
+ * We support three types of lists:
+ *
+ *	T_List: lists of pointers
+ *		(in practice usually pointers to Nodes, but not always;
+ *		declared as "void *" to minimize casting annoyances)
+ *	T_IntList: lists of integers
+ *	T_OidList: lists of Oids
+ *
+ * (At the moment, ints and Oids are the same size, but they may not
+ * always be so; try to be careful to maintain the distinction.)

+ * any columns of the base table.  The expressions are ordered by index
+ * column position (but items referencing the same index column can appear

+ * a lossy indexqual.
+ *
+ * indexqual has the same form, but the expressions have been commuted if
+ * necessary to put the indexkeys on the left, and the indexkeys are replaced
+ * by Var nodes identifying the index columns (their varno is INDEX_VAR and
+ * their varattno is the index column number).
+ *
+ * indexorderbyorig is similarly the original form of any ORDER BY expressions

+ * sort-order information from the ORDER BY SortGroupClauses; it's assumed

+ * indexorderbyorig is used at runtime to recheck the ordering, if the index
+ * cannot calculate an accurate ordering.  It is also needed for EXPLAIN.
+ *
+ * indexorderbyops is a list of the OIDs of the operators used to sort the
+ * ORDER BY expressions.  This is used together with indexorderbyorig to
+ * recheck ordering at run time.  (Note that indexorderby, indexorderbyorig,
+ * and indexorderbyops are used for amcanorderbyop cases, not amcanorder.)

+ * Because of this, *all* Vars in the plan node's targetlist, qual, and
+ * index expressions reference index columns and have varno = INDEX_VAR.
+ *
+ * We could almost use indexqual directly against the index's output tuple
+ * when rechecking lossy index operators, but that won't work for quals on
+ * index columns that are not retrievable.  Hence, recheckqual is needed
+ * for rechecks: it expresses the same condition as indexqual, but using
+ * only index columns that are retrievable.  (We will not generate an
+ * index-only scan if this is not possible.  An example is that if an
+ * index has table column "x" in a retrievable index column "ind1", plus
+ * an expression f(x) in a non-retrievable column "ind2", an indexable
+ * query on f(x) will use "ind2" in indexqual and f(ind1) in recheckqual.
+ * Without the "ind1" column, an index-only scan would be disallowed.)
+ *
+ * We don't currently need a recheckable equivalent of indexorderby,
+ * because we don't support lossy operators in index ORDER BY.
+ *
+ * To help EXPLAIN interpret the index Vars for display, we provide
+ * indextlist, which represents the contents of the index as a targetlist
+ * with one TLE per index column.  Vars appearing in this list reference
+ * the base table, and this is the only field in the plan node that may

+ * Initially all PlanRowMarks have rti == prti and isParent == false.

+ * entries have rti == child rel's RT index and prti == top parent's RT index,
+ * and can therefore be recognized as children by the fact that prti != rti.
+ * The parent's allMarkTypes field gets the OR of (1<<markType) across all
+ * its children (this definition allows children to use different markTypes).
+ *
+ * The planner also adds resjunk output columns to the plan that carry
+ * information sufficient to identify the locked or fetched rows.  When

+ *		tableoid%u			OID of table

+ * (An inheritance hierarchy could have all three resjunk output columns,
+ * if some children use a different markType than others.)
+ * In all three cases, %u represents the rowmark ID number (rowmarkId).
+ * This number is unique within a plan tree, except that child relation
+ * entries copy their parent's rowmarkId.  (Assigning unique numbers
+ * means we needn't renumber rowmarkIds when flattening subqueries, which

+ * (because it is a FULL join or the input column requires a type coercion).

+ * query-printing purposes.)
+ *
+ * At the end of planning, Var nodes appearing in upper-level plan nodes are
+ * reassigned to point to the outputs of their subplans; for example, in a
+ * join node varno becomes INNER_VAR or OUTER_VAR and varattno becomes the

+ * very many places it's convenient to process a whole query targetlist as a
+ * single expression tree.
+ *
+ * In a SELECT's targetlist, resno should always be equal to the item's
+ * ordinal position (counting from 1).  However, in an INSERT or UPDATE
+ * targetlist, resno represents the attribute number of the destination
+ * column for the item; so there may be missing or out-of-order resnos.
+ * It is even legal to have duplicated resnos; consider
+ *		UPDATE table SET arraycol[1] = ..., arraycol[2] = ..., ...
+ * In an INSERT, the rewriter and planner will normalize the tlist by
+ * reordering it into physical column order and filling in default values
+ * for any columns not assigned values by the original query.  In an UPDATE,
+ * after the rewriter merges multiple assignments for the same column, the
+ * planner extracts the target-column numbers into a separate "update_colnos"
+ * list, and then renumbers the tlist elements serially.  Thus, tlist resnos
+ * match ordinal position in all tlists seen by the executor; but it is wrong
+ * to assume that before planning has happened.
+ *
+ * resname is required to represent the correct column name in non-resjunk
+ * entries of top-level SELECT targetlists, since it will be used as the
+ * column title sent to the frontend.  In most other contexts it is only
+ * a debugging aid, and may be wrong or even NULL.  (In particular, it may
+ * be wrong in a tlist from a stored rule, if the referenced column has been
+ * renamed by ALTER TABLE since the rule was made.  Also, the planner tends
+ * to store NULL rather than look up a valid name for tlist entries in
+ * non-toplevel plan nodes.)  In resjunk entries, resname should be either
+ * a specific system-generated name (such as "ctid") or NULL; anything else
+ * risks confusing ExecGetJunkAttribute!
+ *
+ * ressortgroupref is used in the representation of ORDER BY, GROUP BY, and
+ * DISTINCT items.  Targetlist entries with ressortgroupref=0 are not
+ * sort/group items.  If ressortgroupref>0, then this item is an ORDER BY,
+ * GROUP BY, and/or DISTINCT target value.  No two entries in a targetlist
+ * may have the same nonzero ressortgroupref --- but there is no particular
+ * meaning to the nonzero values, except as tags.  (For example, one must
+ * not assume that lower ressortgroupref means a more significant sort key.)
+ * The order of the associated SortGroupClause lists determine the semantics.
+ *
+ * resorigtbl/resorigcol identify the source of the column, if it is a
+ * simple reference to a column of a base table (or view).  If it is not
+ * a simple reference, these fields are zeroes.
+ *
+ * If resjunk is true then the column is a working column (such as a sort key)
+ * that should be removed from the final output of the query.  Resjunk columns
+ * must have resnos that cannot duplicate any regular column's resno.  Also

+ * will not throw any data-value-dependent errors.  Typically this requires

+ * leakproof.  (It is common to prefer throwing errors for invalid subscripts
+ * in assignments; that's fine, but it makes the operation not leakproof.
+ * In current usage there is no advantage in making assignments leakproof.)
+ *
+ * There is no store_strict flag.  Such behavior would generally be
+ * undesirable, since for example a null subscript in an assignment would
+ * cause the entire container to become NULL.

+ * The transform method is called during parse analysis of a subscripting
+ * construct.  The SubscriptingRef node has been constructed, but some of
+ * its fields still need to be filled in, and the subscript expression(s)
+ * are still in raw form.  The transform method is responsible for doing
+ * parse analysis of each subscript expression (using transformExpr),
+ * coercing the subscripts to whatever type it needs, and building the
+ * refupperindexpr and reflowerindexpr lists from those results.  The
+ * reflowerindexpr list must be empty for an element operation, or the

+ * does not care to support slicing, it can just throw an error if isSlice.)
+ * See array_subscript_transform() for sample code.
+ *
+ * The transform method is also responsible for identifying the result type
+ * of the subscripting operation.  At call, refcontainertype and reftypmod
+ * describe the container type (this will be a base type not a domain), and
+ * refelemtype is set to the container type's pg_type.typelem value.  The
+ * transform method must set refrestype and reftypmod to describe the result
+ * of subscripting.  For arrays, refrestype is set to refelemtype for an
+ * element operation or refcontainertype for a slice, while reftypmod stays
+ * the same in either case; but other types might use other rules.  The
+ * transform method should ignore refcollid, as that's determined later on
+ * during parsing.
+ *
+ * At call, refassgnexpr has not been filled in, so the SubscriptingRef node
+ * always looks like a fetch; refrestype should be set as though for a
+ * fetch, too.  (The isAssignment parameter is typically only useful if the
+ * transform method wishes to throw an error for not supporting assignment.)
+ * To complete processing of an assignment, the core parser will coerce the
+ * element/slice source expression to the returned refrestype and reftypmod

+ * reftypmod to again describe the container type, since that's what an

+ * sbs_fetch: perform a subscripting fetch, using the container value in

+ * sbs_check_subscripts, and the new element/slice value in
+ * sbsrefstate->replacevalue/replacenull.  Any of these inputs might be NULL
+ * (unless sbs_check_subscripts rejected null subscripts).  Place the result
+ * (an entire new container value) in *op->resvalue / *op->resnull.
+ *
+ * sbs_fetch_old: this is only used in cases where an element or slice

+ *
+ * Subscripting implementations that do not support assignment need not
+ * provide sbs_assign or sbs_fetch_old methods.  It might be reasonable
+ * to also omit sbs_check_subscripts, in which case the sbs_fetch method must
+ * combine the functionality of sbs_check_subscripts and sbs_fetch.  (The

+ * when a LIKE with constant prefix gives rise to both >= and < conditions.)
+ *
+ * "Directly indexable" means that the condition must be directly executable
+ * by the index machinery.  Typically this means that it is a binary OpExpr
+ * with the index column value on the left, a pseudo-constant on the right,
+ * and an operator that is in the index column's operator family.  Other
+ * possibilities include RowCompareExpr, ScalarArrayOpExpr, and NullTest,
+ * depending on the index type; but those seem less likely to be useful for
+ * derived index conditions.  "Pseudo-constant" means that the right-hand
+ * expression must not contain any volatile functions, nor any Vars of the
+ * table the index is for; use is_pseudo_constant_for_index() to check this.
+ * (Note: if the passed "node" is an OpExpr, the core planner already verified
+ * that the non-indexkey operand is pseudo-constant; but when the "node"
+ * is a FuncExpr, it does not check, since it doesn't know which of the
+ * function's arguments you might need to use in an index comparison value.)
+ *
+ * In many cases, an index condition can be generated but it is weaker than
+ * the function condition itself; for example, a LIKE with a constant prefix
+ * can produce an index range check based on the prefix, but we still need
+ * to execute the LIKE operator to verify the rest of the pattern.  We say
+ * that such an index condition is "lossy".  When returning an index condition,
+ * you should set the "lossy" request field to true if the condition is lossy,
+ * or false if it is an exact equivalent of the function's result.  The core
+ * code will initialize that field to true, which is the common case.
+ *
+ * It is important to verify that the index operator family is the correct
+ * one for the condition you want to generate.  Core support functions tend
+ * to use the known OID of a built-in opfamily for this, but extensions need
+ * to work harder, since their OIDs aren't fixed.  A possibly workable
+ * answer for an index on an extension datatype is to verify the index AM's
+ * OID instead, and then assume that there's only one relevant opclass for
+ * your datatype so the opfamily must be the right one.  Generating OpExpr
+ * nodes may also require knowing extension datatype OIDs (often you can
+ * find these out by applying exprType() to a function argument) and
+ * operator OIDs (which you can look up using get_opfamily_member).

+ * memory with this data structure, we support "lossy" storage, in which
+ * we no longer remember individual tuple offsets on a page but only the
+ * fact that a particular page needs to be visited.

+ * analyzed, or NULL if not available.  (The string is used only to
+ * generate cursor positions in error messages: we need it to convert
+ * byte-wise locations in parse structures to character-wise cursor
+ * positions.)
+ *
+ * p_rtable: list of RTEs that will become the rangetable of the query.
+ * Note that neither relname nor refname of these entries are necessarily
+ * unique; searching the rtable by name is a bad idea.
+ *
+ * p_joinexprs: list of JoinExpr nodes associated with p_rtable entries.
+ * This is one-for-one with p_rtable, but contains NULLs for non-join
+ * RTEs, and may be shorter than p_rtable if the last RTE(s) aren't joins.
+ *
+ * p_joinlist: list of join items (RangeTblRef and JoinExpr nodes) that
+ * will become the fromlist of the query's top-level FromExpr node.
+ *
+ * p_namespace: list of ParseNamespaceItems that represents the current
+ * namespace for table and column lookup.  (The RTEs listed here may be just
+ * a subset of the whole rtable.  See ParseNamespaceItem comments below.)
+ *
+ * p_lateral_active: true if we are currently parsing a LATERAL subexpression
+ * of this parse level.  This makes p_lateral_only namespace items visible,
+ * whereas they are not visible when p_lateral_active is FALSE.
+ *
+ * p_ctenamespace: list of CommonTableExprs (WITH items) that are visible
+ * at the moment.  This is entirely different from p_namespace because a CTE
+ * is not an RTE, rather "visibility" means you could make an RTE from it.
+ *
+ * p_future_ctes: list of CommonTableExprs (WITH items) that are not yet
+ * visible due to scope rules.  This is used to help improve error messages.
+ *
+ * p_parent_cte: CommonTableExpr that immediately contains the current query,
+ * if any.
+ *
+ * p_target_relation: target relation, if query is INSERT/UPDATE/DELETE/MERGE
+ *
+ * p_target_nsitem: target relation's ParseNamespaceItem.
+ *
+ * p_is_insert: true to process assignment expressions like INSERT, false
+ * to process them like UPDATE.  (Note this can change intra-statement, for
+ * cases like INSERT ON CONFLICT UPDATE.)
+ *
+ * p_windowdefs: list of WindowDefs representing WINDOW and OVER clauses.
+ * We collect these while transforming expressions and then transform them
+ * afterwards (so that any resjunk tlist items needed for the sort/group
+ * clauses end up at the end of the query tlist).  A WindowDef's location in
+ * this list, counting from 1, is the winref number to use to reference it.
+ *
+ * p_expr_kind: kind of expression we're currently parsing, as per enum above;
+ * EXPR_KIND_NONE when not in an expression.
+ *
+ * p_next_resno: next TargetEntry.resno to assign, starting from 1.

+ *
+ * p_locked_from_parent: true if parent query level applies FOR UPDATE/SHARE
+ * to this subquery as a whole.
+ *
+ * p_resolve_unknowns: resolve unknown-type SELECT output columns as type TEXT
+ * (this is true by default).
+ *
+ * p_hasAggs, p_hasWindowFuncs, etc: true if we've found any of the indicated
+ * constructs in the query.
+ *
+ * p_last_srf: the set-returning FuncExpr or OpExpr most recently found in
+ * the query, or NULL if none.
+ *

+ * PartitionBoundInfoData encapsulates a set of partition bounds. It is
+ * usually associated with partitioned tables as part of its partition
+ * descriptor, but may also be used to represent a virtual partitioned
+ * table such as a partitioned joinrel within the planner.
+ *
+ * A list partition datum that is known to be NULL is never put into the
+ * datums array. Instead, it is tracked using the null_index field.
+ *
+ * In the case of range partitioning, ndatums will typically be far less than
+ * 2 * nparts, because a partition's upper bound and the next partition's lower
+ * bound are the same in most common cases, and we only store one of them (the
+ * upper bound).  In case of hash partitioning, ndatums will be the same as the
+ * number of partitions.
+ *
+ * For range and list partitioned tables, datums is an array of datum-tuples
+ * with key->partnatts datums each.  For hash partitioned tables, it is an array
+ * of datum-tuples with 2 datums, modulus and remainder, corresponding to a
+ * given partition.
+ *
+ * The datums in datums array are arranged in increasing order as defined by
+ * functions qsort_partition_rbound_cmp(), qsort_partition_list_value_cmp() and
+ * qsort_partition_hbound_cmp() for range, list and hash partitioned tables
+ * respectively. For range and list partitions this simply means that the
+ * datums in the datums array are arranged in increasing order as defined by
+ * the partition key's operator classes and collations.
+ *
+ * In the case of list partitioning, the indexes array stores one entry for
+ * each datum-array entry, which is the index of the partition that accepts
+ * rows matching that datum.  So nindexes == ndatums.
+ *
+ * In the case of range partitioning, the indexes array stores one entry per
+ * distinct range datum, which is the index of the partition for which that
+ * datum is an upper bound (or -1 for a "gap" that has no partition).  It is
+ * convenient to have an extra -1 entry representing values above the last
+ * range datum, so nindexes == ndatums + 1.
+ *
+ * In the case of hash partitioning, the number of entries in the indexes
+ * array is the same as the greatest modulus amongst all partitions (which
+ * is a multiple of all partition moduli), so nindexes == greatest modulus.
+ * The indexes array is indexed according to the hash key's remainder modulo
+ * the greatest modulus, and it contains either the partition index accepting
+ * that remainder, or -1 if there is no partition for that remainder.
+ *
+ * For LIST partitioned tables, we track the partition indexes of partitions
+ * which are possibly "interleaved" partitions.  A partition is considered
+ * interleaved if it allows multiple values and there exists at least one
+ * other partition which could contain a value that lies between those values.
+ * For example, if a partition exists FOR VALUES IN(3,5) and another partition
+ * exists FOR VALUES IN (4), then the IN(3,5) partition is an interleaved
+ * partition.  The same is possible with DEFAULT partitions since they can
+ * contain any value that does not belong in another partition.  This field
+ * only serves as proof that a particular partition is not interleaved, not
+ * proof that it is interleaved.  When we're uncertain, we marked the
+ * partition as interleaved.  The interleaved_parts field is only ever set for
+ * RELOPT_BASEREL and RELOPT_OTHER_MEMBER_REL, it is always left NULL for join
+ * relations.

+ *	Signal stuff
+ *
+ *	For WIN32, there is no wait() call so there are no wait() macros
+ *	to interpret the return value of system().  Instead, system()
+ *	return values < 0x100 are used for exit() termination, and higher
+ *	values are used to indicate non-exit() termination, which is
+ *	similar to a unix-style signal exit (think SIGSEGV ==
+ *	STATUS_ACCESS_VIOLATION).  Return values are broken up into groups:
+ *
+ *	https://docs.microsoft.com/en-us/windows-hardware/drivers/kernel/using-ntstatus-values
+ *
+ *		NT_SUCCESS			0 - 0x3FFFFFFF
+ *		NT_INFORMATION		0x40000000 - 0x7FFFFFFF
+ *		NT_WARNING			0x80000000 - 0xBFFFFFFF
+ *		NT_ERROR			0xC0000000 - 0xFFFFFFFF
+ *
+ *	Effectively, we don't care on the severity of the return value from
+ *	system(), we just need to know if it was because of exit() or generated
+ *	by the system, and it seems values >= 0x100 are system-generated.
+ *	See this URL for a list of WIN32 STATUS_* values:
+ *
+ *		Wine (URL used in our error messages) -
+ *			http://source.winehq.org/source/include/ntstatus.h
+ *		Descriptions -
+ *			https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/596a1078-e883-4972-9bbc-49e60bebca55
+ *
+ *	The comprehensive exception list is included in ntstatus.h from the
+ *	Windows	Driver Kit (WDK).  A subset of the list is also included in
+ *	winnt.h from the Windows SDK.  Defining WIN32_NO_STATUS before including
+ *	windows.h helps to avoid any conflicts.
+ *
+ *	Some day we might want to print descriptions for the most common
+ *	exceptions, rather than printing an include file name.  We could use
+ *	RtlNtStatusToDosError() and pass to FormatMessage(), which can print

+ *
+ * This file provides an abstraction layer to hide portability issues in
+ * interval timing.  On Unix we use clock_gettime() if available, else

+ * for it are:
+ *
+ * INSTR_TIME_IS_ZERO(t)			is t equal to zero?
+ *
+ * INSTR_TIME_SET_ZERO(t)			set t to zero (memset is acceptable too)
+ *
+ * INSTR_TIME_SET_CURRENT(t)		set t to current time
+ *
+ * INSTR_TIME_SET_CURRENT_LAZY(t)	set t to current time if t is zero,
+ *									evaluates to whether t changed
+ *
+ * INSTR_TIME_ADD(x, y)				x += y
+ *
+ * INSTR_TIME_SUBTRACT(x, y)		x -= y
+ *
+ * INSTR_TIME_ACCUM_DIFF(x, y, z)	x += (y - z)

+ *		POSTGRES pluggable background workers interface
+ *
+ * A background worker is a process able to run arbitrary, user-supplied code,
+ * including normal transactions.
+ *
+ * Any external module loaded via shared_preload_libraries can register a
+ * worker.  Workers can also be registered dynamically at runtime.  In either
+ * case, the worker process is forked from the postmaster and runs the
+ * user-supplied "main" function.  This code may connect to a database and
+ * run transactions.  Workers can remain active indefinitely, but will be
+ * terminated if a shutdown or crash occurs.
+ *
+ * If the fork() call fails in the postmaster, it will try again later.  Note
+ * that the failure can only be transient (fork failure due to high load,
+ * memory pressure, too many processes, etc); more permanent problems, like
+ * failure to connect to a database, are detected later in the worker and dealt
+ * with just by having the worker exit normally. A worker which exits with
+ * a return code of 0 will never be restarted and will be removed from worker

+ * that, without much loss of performance.  The "something more complex" is a
+ * 2-D array of color entries, where row indexes correspond to individual chrs
+ * or chr ranges that have been mentioned in the regex (with row zero
+ * representing all other chrs), and column indexes correspond to different
+ * sets of locale-dependent character classes such as "isalpha".  The
+ * classbits[k] entry is zero if we do not care about the k'th character class
+ * in this regex, and otherwise it is the bit to be OR'd into the column index
+ * if the character in question is a member of that class.  We find the color
+ * of a high-valued chr by identifying which colormaprange it is in to get
+ * the row index (use row zero if it's in none of them), identifying which of
+ * the interesting cclasses it's in to get the column index, and then indexing
+ * into the 2-D hicolormap array.

+ * Note: Buffer header lock (BM_LOCKED flag) must be held to examine or change
+ * tag, state or wait_backend_pgprocno fields.  In general, buffer header lock
+ * is a spinlock which is combined with flags, refcount and usagecount into
+ * single atomic variable.  This layout allow us to do some operations in a
+ * single atomic operation, without actually acquiring and releasing spinlock;
+ * for instance, increase or decrease refcount.  buf_id field never changes
+ * after initialization, so does not need locking.  freeNext is protected by
+ * the buffer_strategy_lock not buffer header lock.  The LWLock can take care
+ * of itself.  The buffer header lock is *not* used to control access to the
+ * data in the buffer!
+ *
+ * It's assumed that nobody changes the state field while buffer header lock
+ * is held.  Thus buffer header lock holder can do complex updates of the
+ * state variable in single write, simultaneously with lock release (cleaning
+ * BM_LOCKED flag).  On the other hand, updating of state without holding
+ * buffer header lock is restricted to CAS, which insure that BM_LOCKED flag
+ * is not set.  Atomic increment/decrement, OR/AND etc. are not allowed.
+ *
+ * An exception is that if we have the buffer pinned, its tag can't change
+ * underneath us, so we can examine the tag without locking the buffer header.
+ * Also, in places we do one-time reads of the flags without bothering to
+ * lock the buffer header; this is generally for situations where we don't
+ * expect the flag bit being tested to be changing.
+ *
+ * We can't physically remove items from a disk page if another backend has
+ * the buffer pinned.  Hence, a backend may need to wait for all other pins
+ * to go away.  This is signaled by storing its own pgprocno into
+ * wait_backend_pgprocno and setting flag bit BM_PIN_COUNT_WAITER.  At present,
+ * there can be only one such waiter per buffer.
+ *
+ * We use this same struct for local buffer headers, but the locks are not
+ * used and not all of the flag bits are useful either. To avoid unnecessary
+ * overhead, manipulations of the state field should be done without actual
+ * atomic operations (i.e. only pg_atomic_read_u32() and
+ * pg_atomic_unlocked_write_u32()).
+ *
+ * Be careful to avoid increasing the size of the struct when adding or
+ * reordering members.  Keeping it below 64 bytes (the most common CPU
+ * cache line size) is fairly important for performance.
+ *
+ * Per-buffer I/O condition variables are currently kept outside this struct in
+ * a separate array.  They could be moved in here and still fit within that
+ * limit on common systems, but for now that is not done.

+ * A postgres disk page is an abstraction layered on top of a postgres
+ * disk block (which is simply a unit of i/o, see block.h).
+ *
+ * specifically, while a disk block can be unformatted, a postgres
+ * disk page is always a slotted page of the form:

+ * +----------------+---------------------------------+
+ * | PageHeaderData | linp1 linp2 linp3 ...           |
+ * +-----------+----+---------------------------------+

+ * +-------------+------------------+-----------------+
+ * |	   ... tuple3 tuple2 tuple1 | "special space" |
+ * +--------------------------------+-----------------+
+ *									^ pd_special
+ *
+ * a page is full when nothing can be added between pd_lower and
+ * pd_upper.
+ *
+ * all blocks written out by an access method must be disk pages.
+ *
+ * EXCEPTIONS:
+ *
+ * obviously, a page is not formatted before it is initialized by
+ * a call to PageInit.
+ *
+ * NOTES:
+ *
+ * linp1..N form an ItemId (line pointer) array.  ItemPointers point
+ * to a physical block number and a logical offset (line pointer
+ * number) within that block/page.  Note that OffsetNumbers
+ * conventionally start at 1, not 0.
+ *
+ * tuple1..N are added "backwards" on the page.  Since an ItemPointer
+ * offset is used to access an ItemId entry rather than an actual
+ * byte-offset position, tuples can be physically shuffled on a page
+ * whenever the need arises.  This indirection also keeps crash recovery
+ * relatively simple, because the low-level details of page space
+ * management can be controlled by standard buffer page code during
+ * logging, and during recovery.
+ *
+ * AM-generic per-page information is kept in PageHeaderData.
+ *
+ * AM-specific per-page data (if any) is kept in the area marked "special
+ * space"; each AM has an "opaque" structure defined somewhere that is

+ *
+ * The LSN is used by the buffer manager to enforce the basic rule of WAL:
+ * "thou shalt write xlog before data".  A dirty buffer cannot be dumped
+ * to disk until xlog has been flushed at least as far as the page's LSN.
+ *
+ * pd_checksum stores the page checksum, if it has been set for this page;
+ * zero is a valid value for a checksum. If a checksum is not in use then
+ * we leave the field unset. This will typically mean the field is zero
+ * though non-zero values may also be present if databases have been
+ * pg_upgraded from releases prior to 9.3, when the same byte offset was
+ * used to store the current timelineid when the page was last updated.
+ * Note that there is no indication on a page as to whether the checksum
+ * is valid or not, a deliberate design choice which avoids the problem
+ * of relying on the page contents to decide whether to verify it. Hence

+ * The page version number and page size are packed together into a single

+ * there was no concept of a page version number, and doing it this way
+ * lets us pretend that pre-7.3 databases have page version number zero.
+ * We constrain page sizes to be multiples of 256, leaving the low eight
+ * bits available for a version number.
+ *
+ * Minimum possible page size is perhaps 64B to fit page header, opaque space
+ * and a minimal tuple; of course, in reality you want it much bigger, so

+ * The algorithm used to checksum pages is chosen for very fast calculation.
+ * Workloads where the database working set fits into OS file cache but not
+ * into shared buffers can read in pages at a very fast pace and the checksum
+ * algorithm itself can become the largest bottleneck.
+ *
+ * The checksum algorithm itself is based on the FNV-1a hash (FNV is shorthand
+ * for Fowler/Noll/Vo).  The primitive of a plain FNV-1a hash folds in data 1
+ * byte at a time according to the formula:
+ *
+ *	   hash = (hash ^ value) * FNV_PRIME
+ *
+ * FNV-1a algorithm is described at http://www.isthe.com/chongo/tech/comp/fnv/
+ *
+ * PostgreSQL doesn't use FNV-1a hash directly because it has bad mixing of
+ * high bits - high order bits in input data only affect high order bits in
+ * output data. To resolve this we xor in the value prior to multiplication
+ * shifted right by 17 bits. The number 17 was chosen because it doesn't
+ * have common denominator with set bit positions in FNV_PRIME and empirically
+ * provides the fastest mixing for high order bits of final iterations quickly
+ * avalanche into lower positions. For performance reasons we choose to combine
+ * 4 bytes at a time. The actual hash formula used as the basis is:
+ *
+ *	   hash = (hash ^ value) * FNV_PRIME ^ ((hash ^ value) >> 17)
+ *
+ * The main bottleneck in this calculation is the multiplication latency. To
+ * hide the latency and to make use of SIMD parallelism multiple hash values
+ * are calculated in parallel. The page is treated as a 32 column two
+ * dimensional array of 32 bit values. Each column is aggregated separately
+ * into a partial checksum. Each partial checksum uses a different initial
+ * value (offset basis in FNV terminology). The initial values actually used
+ * were chosen randomly, as the values themselves don't matter as much as that
+ * they are different and don't match anything in real data. After initializing
+ * partial checksums each value in the column is aggregated according to the
+ * above formula. Finally two more iterations of the formula are performed with
+ * value 0 to mix the bits of the last value added.
+ *
+ * The partial checksums are then folded together using xor to form a single
+ * 32-bit checksum. The caller can safely reduce the value to 16 bits
+ * using modulo 2^16-1. That will cause a very slight bias towards lower
+ * values but this is not significant for the performance of the
+ * checksum.
+ *
+ * The algorithm choice was based on what instructions are available in SIMD
+ * instruction sets. This meant that a fast and good algorithm needed to use
+ * multiplication as the main mixing operator. The simplest multiplication
+ * based checksum primitive is the one used by FNV. The prime used is chosen
+ * for good dispersion of values. It has no known simple patterns that result
+ * in collisions. Test of 5-bit differentials of the primitive over 64bit keys
+ * reveals no differentials with 3 or more values out of 100000 random keys
+ * colliding. Avalanche test shows that only high order bits of the last word
+ * have a bias. Tests of 1-4 uncorrelated bit errors, stray 0 and 0xFF bytes,
+ * overwriting page from random position to end with 0 bytes, and overwriting
+ * random segments of page with 0x00, 0xFF and random data all show optimal
+ * 2e-16 false positive rate within margin of error.
+ *
+ * Vectorization of the algorithm requires 32bit x 32bit -> 32bit integer
+ * multiplication instruction. As of 2013 the corresponding instruction is
+ * available on x86 SSE4.1 extensions (pmulld) and ARM NEON (vmul.i32).
+ * Vectorization requires a compiler to do the vectorization for us. For recent
+ * GCC versions the flags -msse4.1 -funroll-loops -ftree-vectorize are enough
+ * to achieve vectorization.
+ *
+ * The optimal amount of parallelism to use depends on CPU specific instruction
+ * latency, SIMD instruction width, throughput and the amount of registers
+ * available to hold intermediate state. Generally, more parallelism is better
+ * up to the point that state doesn't fit in registers and extra load-store
+ * instructions are needed to swap values in/out. The number chosen is a fixed
+ * part of the algorithm because changing the parallelism changes the checksum
+ * result.
+ *
+ * The parallelism number 32 was chosen based on the fact that it is the
+ * largest state that fits into architecturally visible x86 SSE registers while
+ * leaving some free registers for intermediate values. For future processors
+ * with 256bit vector registers this will leave some performance on the table.
+ * When vectorization is not available it might be beneficial to restructure
+ * the computation to calculate a subset of the columns at a time and perform
+ * multiple passes to avoid register spilling. This optimization opportunity
+ * is not used. Current coding also assumes that the compiler has the ability
+ * to unroll the inner loop to avoid loop overhead and minimize register
+ * spilling. For less sophisticated compilers it might be beneficial to
+ * manually unroll the inner loop.

+/*-------------------------------------------------------------------------
+ *
+ * latch.h
+ *	  Routines for interprocess latches
+ *
+ * A latch is a boolean variable, with operations that let processes sleep
+ * until it is set. A latch can be set from another process, or a signal
+ * handler within the same process.
+ *
+ * The latch interface is a reliable replacement for the common pattern of
+ * using pg_usleep() or select() to wait until a signal arrives, where the
+ * signal handler sets a flag variable. Because on some platforms an
+ * incoming signal doesn't interrupt sleep, and even on platforms where it
+ * does there is a race condition if the signal arrives just before
+ * entering the sleep, the common pattern must periodically wake up and
+ * poll the flag variable. The pselect() system call was invented to solve
+ * this problem, but it is not portable enough. Latches are designed to
+ * overcome these limitations, allowing you to sleep without polling and
+ * ensuring quick response to signals from other processes.
+ *
+ * There are two kinds of latches: local and shared. A local latch is
+ * initialized by InitLatch, and can only be set from the same process.
+ * A local latch can be used to wait for a signal to arrive, by calling
+ * SetLatch in the signal handler. A shared latch resides in shared memory,
+ * and must be initialized at postmaster startup by InitSharedLatch. Before
+ * a shared latch can be waited on, it must be associated with a process
+ * with OwnLatch. Only the process owning the latch can wait on it, but any
+ * process can set it.
+ *
+ * There are three basic operations on a latch:
+ *
+ * SetLatch		- Sets the latch
+ * ResetLatch	- Clears the latch, allowing it to be set again
+ * WaitLatch	- Waits for the latch to become set
+ *
+ * WaitLatch includes a provision for timeouts (which should be avoided
+ * when possible, as they incur extra overhead) and a provision for
+ * postmaster child processes to wake up immediately on postmaster death.
+ * See latch.c for detailed specifications for the exported functions.
+ *
+ * The correct pattern to wait for event(s) is:
+ *
+ * for (;;)
+ * {
+ *	   ResetLatch();
+ *	   if (work to do)
+ *		   Do Stuff();
+ *	   WaitLatch();
+ * }
+ *
+ * It's important to reset the latch *before* checking if there's work to
+ * do. Otherwise, if someone sets the latch between the check and the
+ * ResetLatch call, you will miss it and Wait will incorrectly block.
+ *
+ * Another valid coding pattern looks like:
+ *
+ * for (;;)
+ * {
+ *	   if (work to do)
+ *		   Do Stuff(); // in particular, exit loop if some condition satisfied
+ *	   WaitLatch();
+ *	   ResetLatch();
+ * }
+ *
+ * This is useful to reduce latch traffic if it's expected that the loop's
+ * termination condition will often be satisfied in the first iteration;
+ * the cost is an extra loop iteration before blocking when it is not.
+ * What must be avoided is placing any checks for asynchronous events after
+ * WaitLatch and before ResetLatch, as that creates a race condition.
+ *
+ * To wake up the waiter, you must first set a global flag or something
+ * else that the wait loop tests in the "if (work to do)" part, and call
+ * SetLatch *after* that. SetLatch is designed to return quickly if the
+ * latch is already set.
+ *
+ * On some platforms, signals will not interrupt the latch wait primitive
+ * by themselves.  Therefore, it is critical that any signal handler that
+ * is meant to terminate a WaitLatch wait calls SetLatch.
+ *
+ * Note that use of the process latch (PGPROC.procLatch) is generally better
+ * than an ad-hoc shared latch for signaling auxiliary processes.  This is
+ * because generic signal handlers will call SetLatch on the process latch
+ * only, so using any latch other than the process latch effectively precludes
+ * use of any generic handler.
+ *
+ *
+ * WaitEventSets allow to wait for latches being set and additional events -
+ * postmaster dying and socket readiness of several sockets currently - at the
+ * same time.  On many platforms using a long lived event set is more
+ * efficient than using WaitLatch or WaitLatchOrSocket.

+ * maintained in both places in a coherent manner.
+ *
+ * The denser separate arrays are beneficial for three main reasons: First, to
+ * allow for as tight loops accessing the data as possible. Second, to prevent
+ * updates of frequently changing data (e.g. xmin) from invalidating
+ * cachelines also containing less frequently changing data (e.g. xid,
+ * statusFlags). Third to condense frequently accessed data into as few
+ * cachelines as possible.
+ *
+ * There are two main reasons to have the data mirrored between these dense
+ * arrays and PGPROC. First, as explained above, a PGPROC's array entries can
+ * only be accessed with either ProcArrayLock or XidGenLock held, whereas the
+ * PGPROC entries do not require that (obviously there may still be locking
+ * requirements around the individual field, separate from the concerns
+ * here). That is particularly important for a backend to efficiently checks
+ * it own values, which it often can safely do without locking.  Second, the
+ * PGPROC fields allow to avoid unnecessary accesses and modification to the
+ * dense arrays. A backend's own PGPROC is more likely to be in a local cache,
+ * whereas the cachelines for the dense array will be modified by other
+ * backends (often removing it from the cache for other cores/sockets). At
+ * commit/abort time a check of the PGPROC value can avoid accessing/dirtying
+ * the corresponding array value.
+ *
+ * Basically it makes sense to access the PGPROC variable when checking a
+ * single backend's data, especially when already looking at the PGPROC for
+ * other reasons already.  It makes sense to look at the "dense" arrays if we
+ * need to look at many / most entries, because we then benefit from the
+ * reduced indirection and better cross-process cache-ability.
+ *
+ * When entering a PGPROC for 2PC transactions with ProcArrayAdd(), the data
+ * in the dense arrays is initialized from the PGPROC while it already holds
+ * ProcArrayLock.

+ *
+ * s_lock.h
+ *	   Hardware-dependent implementation of spinlocks.
+ *
+ *	NOTE: none of the macros in this file are intended to be called directly.
+ *	Call them through the hardware-independent macros in spin.h.
+ *
+ *	The following hardware-dependent macros must be provided for each
+ *	supported platform:
+ *
+ *	void S_INIT_LOCK(slock_t *lock)
+ *		Initialize a spinlock (to the unlocked state).
+ *
+ *	int S_LOCK(slock_t *lock)
+ *		Acquire a spinlock, waiting if necessary.
+ *		Time out and abort() if unable to acquire the lock in a
+ *		"reasonable" amount of time --- typically ~ 1 minute.
+ *		Should return number of "delays"; see s_lock.c
+ *
+ *	void S_UNLOCK(slock_t *lock)
+ *		Unlock a previously acquired lock.
+ *
+ *	bool S_LOCK_FREE(slock_t *lock)
+ *		Tests if the lock is free. Returns true if free, false if locked.
+ *		This does *not* change the state of the lock.
+ *
+ *	void SPIN_DELAY(void)
+ *		Delay operation to occur inside spinlock wait loop.
+ *
+ *	Note to implementors: there are default implementations for all these
+ *	macros at the bottom of the file.  Check if your platform can use
+ *	these or needs to override them.
+ *
+ *  Usually, S_LOCK() is implemented in terms of even lower-level macros
+ *	TAS() and TAS_SPIN():
+ *
+ *	int TAS(slock_t *lock)
+ *		Atomic test-and-set instruction.  Attempt to acquire the lock,
+ *		but do *not* wait.	Returns 0 if successful, nonzero if unable
+ *		to acquire the lock.
+ *
+ *	int TAS_SPIN(slock_t *lock)
+ *		Like TAS(), but this version is used when waiting for a lock
+ *		previously found to be contended.  By default, this is the
+ *		same as TAS(), but on some architectures it's better to poll a
+ *		contended lock using an unlocked instruction and retry the
+ *		atomic test-and-set only when it appears free.
+ *
+ *	TAS() and TAS_SPIN() are NOT part of the API, and should never be called
+ *	directly.
+ *
+ *	CAUTION: on some platforms TAS() and/or TAS_SPIN() may sometimes report
+ *	failure to acquire a lock even when the lock is not locked.  For example,
+ *	on Alpha TAS() will "fail" if interrupted.  Therefore a retry loop must
+ *	always be used, even if you are certain the lock is free.
+ *
+ *	It is the responsibility of these macros to make sure that the compiler
+ *	does not re-order accesses to shared memory to precede the actual lock
+ *	acquisition, or follow the lock release.  Prior to PostgreSQL 9.5, this
+ *	was the caller's responsibility, which meant that callers had to use
+ *	volatile-qualified pointers to refer to both the spinlock itself and the
+ *	shared data being accessed within the spinlocked critical section.  This
+ *	was notationally awkward, easy to forget (and thus error-prone), and
+ *	prevented some useful compiler optimizations.  For these reasons, we
+ *	now require that the macros themselves prevent compiler re-ordering,
+ *	so that the caller doesn't need to take special precautions.
+ *
+ *	On platforms with weak memory ordering, the TAS(), TAS_SPIN(), and
+ *	S_UNLOCK() macros must further include hardware-level memory fence
+ *	instructions to prevent similar re-ordering at the hardware level.
+ *	TAS() and TAS_SPIN() must guarantee that loads and stores issued after
+ *	the macro are not executed until the lock has been obtained.  Conversely,
+ *	S_UNLOCK() must guarantee that loads and stores issued before the macro
+ *	have been executed before the lock is released.
+ *
+ *	On most supported platforms, TAS() uses a tas() function written
+ *	in assembly language to execute a hardware atomic-test-and-set
+ *	instruction.  Equivalent OS-supplied mutex routines could be used too.
+ *
+ *	If no system-specific TAS() is available (ie, HAVE_SPINLOCKS is not
+ *	defined), then we fall back on an emulation that uses SysV semaphores
+ *	(see spin.c).  This emulation will be MUCH MUCH slower than a proper TAS()
+ *	implementation, because of the cost of a kernel call per lock or unlock.
+ *	An old report is that Postgres spends around 40% of its time in semop(2)
+ *	when using the SysV semaphore code.

+ *	* invalidate all catcache entries from a given system catalog
+ *	* invalidate a relcache entry for a specific logical relation
+ *	* invalidate all relcache entries
+ *	* invalidate an smgr cache entry for a specific physical relation
+ *	* invalidate the mapped-relation mapping for a given database
+ *	* invalidate any saved snapshot that might be used to scan a given relation
+ * More types could be added if needed.  The message type is identified by
+ * the first "int8" field of the message struct.  Zero or positive means a
+ * specific-catcache inval message (and also serves as the catcache ID field).
+ * Negative values identify the other message types, as per codes below.
+ *
+ * Catcache inval events are initially driven by detecting tuple inserts,
+ * updates and deletions in system catalogs (see CacheInvalidateHeapTuple).
+ * An update can generate two inval events, one for the old tuple and one for
+ * the new, but this is reduced to one event if the tuple's hash key doesn't
+ * change.  Note that the inval events themselves don't actually say whether
+ * the tuple is being inserted or deleted.  Also, since we transmit only a
+ * hash key, there is a small risk of unnecessary invalidations due to chance
+ * matches of hash keys.
+ *
+ * Note that some system catalogs have multiple caches on them (with different
+ * indexes).  On detecting a tuple invalidation in such a catalog, separate
+ * catcache inval messages must be generated for each of its caches, since
+ * the hash keys will generally be different.
+ *
+ * Catcache, relcache, and snapshot invalidations are transactional, and so
+ * are sent to other backends upon commit.  Internally to the generating
+ * backend, they are also processed at CommandCounterIncrement so that later
+ * commands in the same transaction see the new state.  The generating backend
+ * also has to process them at abort, to flush out any cache state it's loaded
+ * from no-longer-valid entries.
+ *
+ * smgr and relation mapping invalidations are non-transactional: they are
+ * sent immediately when the underlying file change is made.

+ *
+ * dest.h
+ *	  support for communication destinations
+ *
+ * Whenever the backend executes a query that returns tuples, the results
+ * have to go someplace.  For example:
+ *
+ *	  - stdout is the destination only when we are running a
+ *		standalone backend (no postmaster) and are returning results
+ *		back to an interactive user.
+ *
+ *	  - a remote process is the destination when we are
+ *		running a backend with a frontend and the frontend executes
+ *		PQexec() or PQfn().  In this case, the results are sent
+ *		to the frontend via the functions in backend/libpq.
+ *
+ *	  - DestNone is the destination when the system executes
+ *		a query internally.  The results are discarded.
+ *
+ * dest.c defines three functions that implement destination management:
+ *
+ * BeginCommand: initialize the destination at start of command.
+ * CreateDestReceiver: return a pointer to a struct of destination-specific
+ * receiver functions.
+ * EndCommand: clean up the destination at end of command.
+ *
+ * BeginCommand/EndCommand are executed once per received SQL query.
+ *
+ * CreateDestReceiver returns a receiver object appropriate to the specified
+ * destination.  The executor, as well as utility statements that can return
+ * tuples, are passed the resulting DestReceiver* pointer.  Each executor run
+ * or utility execution calls the receiver's rStartup method, then the
+ * receiveSlot method (zero or more times), then the rShutdown method.
+ * The same receiver object may be re-used multiple times; eventually it is
+ * destroyed by calling its rDestroy method.
+ *
+ * In some cases, receiver objects require additional parameters that must
+ * be passed to them after calling CreateDestReceiver.  Since the set of
+ * parameters varies for different receiver types, this is not handled by
+ * this module, but by direct calls from the calling code to receiver type
+ * specific functions.
+ *
+ * The DestReceiver object returned by CreateDestReceiver may be a statically
+ * allocated object (for destination types that require no local state),
+ * in which case rDestroy is a no-op.  Alternatively it can be a palloc'd
+ * object that has DestReceiver as its first field and contains additional
+ * fields (see printtup.c for an example).  These additional fields are then
+ * accessible to the DestReceiver functions by casting the DestReceiver*
+ * pointer passed to them.  The palloc'd object is pfree'd by the rDestroy
+ * method.  Note that the caller of CreateDestReceiver should take care to
+ * do so in a memory context that is long-lived enough for the receiver
+ * object not to disappear while still needed.
+ *
+ * Special provision: None_Receiver is a permanently available receiver
+ * object for the DestNone destination.  This avoids useless creation/destroy
+ * calls in portal and cursor manipulations.

+ *
+ * NOTES
+ *	  An ACL array is simply an array of AclItems, representing the union
+ *	  of the privileges represented by the individual items.  A zero-length
+ *	  array represents "no privileges".
+ *
+ *	  The order of items in the array is important as client utilities (in
+ *	  particular, pg_dump, though possibly other clients) expect to be able
+ *	  to issue GRANTs in the ordering of the items in the array.  The reason
+ *	  this matters is that GRANTs WITH GRANT OPTION must be before any GRANTs
+ *	  which depend on it.  This happens naturally in the backend during
+ *	  operations as we update ACLs in-place, new items are appended, and
+ *	  existing entries are only removed if there's no dependency on them (no
+ *	  GRANT can been based on it, or, if there was, those GRANTs are also
+ *	  removed).
+ *
+ *	  For backward-compatibility purposes we have to allow null ACL entries
+ *	  in system catalogs.  A null ACL will be treated as meaning "default
+ *	  protection" (i.e., whatever acldefault() returns).

+ * array.h
+ *	  Declarations for Postgres arrays.
+ *
+ * A standard varlena array has the following internal structure:
+ *	  <vl_len_>		- standard varlena header word
+ *	  <ndim>		- number of dimensions of the array
+ *	  <dataoffset>	- offset to stored data, or 0 if no nulls bitmap
+ *	  <elemtype>	- element type OID
+ *	  <dimensions>	- length of each array axis (C array of int)
+ *	  <lower bnds>	- lower boundary of each dimension (C array of int)
+ *	  <null bitmap> - bitmap showing locations of nulls (OPTIONAL)
+ *	  <actual data> - whatever is the stored data
+ *
+ * The <dimensions> and <lower bnds> arrays each have ndim elements.
+ *
+ * The <null bitmap> may be omitted if the array contains no NULL elements.
+ * If it is absent, the <dataoffset> field is zero and the offset to the
+ * stored data must be computed on-the-fly.  If the bitmap is present,
+ * <dataoffset> is nonzero and is equal to the offset from the array start
+ * to the first data element (including any alignment padding).  The bitmap
+ * follows the same conventions as tuple null bitmaps, ie, a 1 indicates
+ * a non-null entry and the LSB of each bitmap byte is used first.
+ *
+ * The actual data starts on a MAXALIGN boundary.  Individual items in the
+ * array are aligned as specified by the array element type.  They are
+ * stored in row-major order (last subscript varies most rapidly).
+ *
+ * NOTE: it is important that array elements of toastable datatypes NOT be
+ * toasted, since the tupletoaster won't know they are there.  (We could
+ * support compressed toasted items; only out-of-line items are dangerous.
+ * However, it seems preferable to store such items uncompressed and allow
+ * the toaster to compress the whole array as one input.)
+ *
+ *
+ * The OIDVECTOR and INT2VECTOR datatypes are storage-compatible with
+ * generic arrays, but they support only one-dimensional arrays with no
+ * nulls (and no null bitmap).  They don't support being toasted, either.
+ *
+ * There are also some "fixed-length array" datatypes, such as NAME and
+ * POINT.  These are simply a sequence of a fixed number of items each
+ * of a fixed-length datatype, with no overhead; the item size must be
+ * a multiple of its alignment requirement, because we do no padding.
+ * We support subscripting on these types, but array_in() and array_out()
+ * only work with varlena arrays.
+ *
+ * In addition, arrays are a major user of the "expanded object" TOAST
+ * infrastructure.  This allows a varlena array to be converted to a
+ * separate representation that may include "deconstructed" Datum/isnull
+ * arrays holding the elements.

+ *				... other errxxx() fields as needed ...);
+ *
+ * The error level is required, and so is a primary error message (errmsg
+ * or errmsg_internal).  All else is optional.  errcode() defaults to
+ * ERRCODE_INTERNAL_ERROR if elevel is ERROR or more, ERRCODE_WARNING
+ * if elevel is WARNING, or ERRCODE_SUCCESSFUL_COMPLETION if elevel is
+ * NOTICE or below.
+ *
+ * Before Postgres v12, extra parentheses were required around the

+ *
+ * ereport_domain() allows a message domain to be specified, for modules that
+ * wish to use a different message catalog from the backend's.  To avoid having
+ * one copy of the default text domain per .o file, we define it as NULL here
+ * and have errstart insert the default text domain.  Modules can either use
+ * ereport_domain() directly, or preferably they can override the TEXTDOMAIN
+ * macro.
+ *
+ * When __builtin_constant_p is available and elevel >= ERROR we make a call
+ * to errstart_cold() instead of errstart().  This version of the function is
+ * marked with pg_attribute_cold which will coax supporting compilers into
+ * generating code which is more optimized towards non-ERROR cases.  Because
+ * we use __builtin_constant_p() in the condition, when elevel is not a
+ * compile-time constant, or if it is, but it's < ERROR, the compiler has no
+ * need to generate any code for this branch.  It can simply call errstart()
+ * unconditionally.
+ *
+ * If elevel >= ERROR, the call will not return; we try to inform the compiler
+ * of that via pg_unreachable().  However, no useful optimization effect is
+ * obtained unless the compiler sees elevel as a compile-time constant, else
+ * we're just adding code bloat.  So, if __builtin_constant_p is available,
+ * use that to cause the second if() to vanish completely for non-constant

+ *
+ * For the common case that the error recovery code and the cleanup in the

+ *
+ * Note: while the system will correctly propagate any new ereport(ERROR)
+ * occurring in the recovery section, there is a small limit on the number
+ * of levels this will work for.  It's best to keep the error recovery
+ * section simple enough that it can't generate any new errors, at least
+ * not before popping the error stack.
+ *
+ * Note: an ereport(FATAL) will not be caught by this construct; control will
+ * exit straight through proc_exit().  Therefore, do NOT put any cleanup
+ * of non-process-local resources into the error recovery section, at least
+ * not without taking thought for what will happen during ereport(FATAL).
+ * The PG_ENSURE_ERROR_CLEANUP macros provided by storage/ipc.h may be
+ * helpful in such cases.
+ *
+ * Note: if a local variable of the function containing PG_TRY is modified

+ *	  Declarations for access to "expanded" value representations.
+ *
+ * Complex data types, particularly container types such as arrays and
+ * records, usually have on-disk representations that are compact but not
+ * especially convenient to modify.  What's more, when we do modify them,
+ * having to recopy all the rest of the value can be extremely inefficient.
+ * Therefore, we provide a notion of an "expanded" representation that is used
+ * only in memory and is optimized more for computation than storage.
+ * The format appearing on disk is called the data type's "flattened"
+ * representation, since it is required to be a contiguous blob of bytes --
+ * but the type can have an expanded representation that is not.  Data types
+ * must provide means to translate an expanded representation back to
+ * flattened form.
+ *
+ * An expanded object is meant to survive across multiple operations, but
+ * not to be enormously long-lived; for example it might be a local variable
+ * in a PL/pgSQL procedure.  So its extra bulk compared to the on-disk format
+ * is a worthwhile trade-off.
+ *
+ * References to expanded objects are a type of TOAST pointer.
+ * Because of longstanding conventions in Postgres, this means that the
+ * flattened form of such an object must always be a varlena object.
+ * Fortunately that's no restriction in practice.
+ *
+ * There are actually two kinds of TOAST pointers for expanded objects:
+ * read-only and read-write pointers.  Possession of one of the latter
+ * authorizes a function to modify the value in-place rather than copying it
+ * as would normally be required.  Functions should always return a read-write
+ * pointer to any new expanded object they create.  Functions that modify an
+ * argument value in-place must take care that they do not corrupt the old
+ * value if they fail partway through.

+ * startup packet (e.g., from libpq's PGOPTIONS variable).  SU_BACKEND
+ * options can be set from the startup packet only when the user is a

+ * to such an option in the configuration file.  The idea is that these
+ * options are fixed for a given backend once it's started, but they can
+ * vary across backends.
+ *

+ * distinguish that this has happened.  Hashing long strings saves space and
+ * ensures that we won't overrun the maximum entry length for a GIN index.
+ * (But JGIN_MAXLENGTH is quite a bit shorter than GIN's limit.  It's chosen
+ * to ensure that the on-disk text datum will have a short varlena header.)

+ * Jsonbs are varlena objects, so must meet the varlena convention that the
+ * first int32 of the object contains the total object size in bytes.  Be sure
+ * to use VARSIZE() and SET_VARSIZE() to access it, though!
+ *
+ * Jsonb is the on-disk representation, in contrast to the in-memory JsonbValue
+ * representation.  Often, JsonbValues are just shims through which a Jsonb
+ * buffer is accessed, but they can also be deep copied and passed around.
+ *
+ * Jsonb is a tree structure. Each node in the tree consists of a JEntry
+ * header and a variable-length content (possibly of zero size).  The JEntry
+ * header indicates what kind of a node it is, e.g. a string or an array,
+ * and provides the length of its variable-length portion.
+ *
+ * The JEntry and the content of a node are not stored physically together.
+ * Instead, the container array or object has an array that holds the JEntrys
+ * of all the child nodes, followed by their variable-length portions.
+ *
+ * The root node is an exception; it has no parent array or object that could
+ * hold its JEntry. Hence, no JEntry header is stored for the root node.  It
+ * is implicitly known that the root node must be an array or an object,
+ * so we can get away without the type indicator as long as we can distinguish
+ * the two.  For that purpose, both an array and an object begin with a uint32
+ * header field, which contains an JB_FOBJECT or JB_FARRAY flag.  When a naked
+ * scalar value needs to be stored as a Jsonb value, what we actually store is
+ * an array with one element, with the flags in the array's header field set
+ * to JB_FSCALAR | JB_FARRAY.
+ *
+ * Overall, the Jsonb struct requires 4-bytes alignment. Within the struct,
+ * the variable-length portion of some node types is aligned to a 4-byte
+ * boundary, while others are not. When alignment is needed, the padding is
+ * in the beginning of the node that requires it. For example, if a numeric
+ * node is stored after a string node, so that the numeric node begins at
+ * offset 3, the variable-length portion of the numeric node will begin with
+ * one padding byte so that the actual numeric data is 4-byte aligned.
+ */
+
+/*
+ * JEntry format.
+ *
+ * The least significant 28 bits store either the data length of the entry,
+ * or its end+1 offset from the start of the variable-length portion of the
+ * containing object.  The next three bits store the type of the entry, and
+ * the high-order bit tells whether the least significant bits store a length
+ * or an offset.
+ *
+ * The reason for the offset-or-length complication is to compromise between
+ * access speed and data compressibility.  In the initial design each JEntry
+ * always stored an offset, but this resulted in JEntry arrays with horrible
+ * compressibility properties, so that TOAST compression of a JSONB did not
+ * work well.  Storing only lengths would greatly improve compressibility,
+ * but it makes random access into large arrays expensive (O(N) not O(1)).
+ * So what we do is store an offset in every JB_OFFSET_STRIDE'th JEntry and
+ * a length in the rest.  This results in reasonably compressible data (as
+ * long as the stride isn't too small).  We may have to examine as many as
+ * JB_OFFSET_STRIDE JEntrys in order to find out the offset or length of any
+ * given item, but that's still O(1) no matter how large the container is.
+ *
+ * We could avoid eating a flag bit for this purpose if we were to store
+ * the stride in the container header, or if we were willing to treat the
+ * stride as an unchangeable constant.  Neither of those options is very
+ * attractive though.

+ * Because the obvious implementation of resetting single-writer stats isn't

+ * shared stats while resetting. Instead, just record the current counter
+ * values in a copy of the stats data, which is protected by ->lock. See
+ * pgstat_fetch_stat_(archiver|bgwriter|checkpointer) for the reader side.
+ *
+ * The only exception to that is the stat_reset_timestamp in these structs,

+ * CachedPlanSource (which might better have been called CachedQuery)
+ * represents a SQL query that we expect to use multiple times.  It stores
+ * the query source text, the raw parse tree, and the analyzed-and-rewritten
+ * query tree, as well as adjunct data.  Cache invalidation can happen as a
+ * result of DDL affecting objects used by the query.  In that case we discard
+ * the analyzed-and-rewritten query tree, and rebuild it when next needed.
+ *
+ * An actual execution plan, represented by CachedPlan, is derived from the
+ * CachedPlanSource when we need to execute the query.  The plan could be
+ * either generic (usable with any set of plan parameters) or custom (for a
+ * specific set of parameters).  plancache.c contains the logic that decides
+ * which way to do it for any particular execution.  If we are using a generic
+ * cached plan then it is meant to be re-used across multiple executions, so
+ * callers must always treat CachedPlans as read-only.
+ *
+ * Once successfully built and "saved", CachedPlanSources typically live
+ * for the life of the backend, although they can be dropped explicitly.
+ * CachedPlans are reference-counted and go away automatically when the last
+ * reference is dropped.  A CachedPlan can outlive the CachedPlanSource it
+ * was created from.
+ *
+ * An "unsaved" CachedPlanSource can be used for generating plans, but it
+ * lives in transient storage and will not be updated in response to sinval
+ * events.
+ *
+ * CachedPlans made from saved CachedPlanSources are likewise in permanent
+ * storage, so to avoid memory leaks, the reference-counted references to them
+ * must be held in permanent data structures or ResourceOwners.  CachedPlans
+ * made from unsaved CachedPlanSources are in children of the caller's
+ * memory context, so references to them should not be longer-lived than
+ * that context.  (Reference counting is somewhat pro forma in that case,
+ * though it may be useful if the CachedPlan can be discarded early.)
+ *
+ * A CachedPlanSource has two associated memory contexts: one that holds the
+ * struct itself, the query source text and the raw parse tree, and another
+ * context that holds the rewritten query tree and associated data.  This
+ * allows the query tree to be discarded easily when it is invalidated.
+ *
+ * Some callers wish to use the CachedPlan API even with one-shot queries
+ * that have no reason to be saved at all.  We therefore support a "oneshot"
+ * variant that does no data copying or invalidation checking.  In this case
+ * there are no separate memory contexts: the CachedPlanSource struct and
+ * all subsidiary data live in the caller's CurrentMemoryContext, and there
+ * is no way to free memory short of clearing that entire context.  A oneshot
+ * plan is always treated as unsaved.
+ *
+ * Note: the string referenced by commandTag is not subsidiary storage;
+ * it is assumed to be a compile-time-constant string.  As with portals,
+ * commandTag shall be NULL if and only if the original query string (before
+ * rewriting) was an empty string.

+ *	  POSTGRES portal definitions.
+ *
+ * A portal is an abstraction which represents the execution state of
+ * a running or runnable query.  Portals support both SQL-level CURSORs
+ * and protocol-level portals.
+ *
+ * Scrolling (nonsequential access) and suspension of execution are allowed
+ * only for portals that contain a single SELECT-type query.  We do not want
+ * to let the client suspend an update-type query partway through!	Because
+ * the query rewriter does not allow arbitrary ON SELECT rewrite rules,
+ * only queries that were originally update-type could produce multiple
+ * plan trees; so the restriction to a single query is not a problem
+ * in practice.
+ *
+ * For SQL cursors, we support three kinds of scroll behavior:
+ *
+ * (1) Neither NO SCROLL nor SCROLL was specified: to remain backward
+ *	   compatible, we allow backward fetches here, unless it would
+ *	   impose additional runtime overhead to do so.
+ *
+ * (2) NO SCROLL was specified: don't allow any backward fetches.
+ *
+ * (3) SCROLL was specified: allow all kinds of backward fetches, even
+ *	   if we need to take a performance hit to do so.  (The planner sticks
+ *	   a Materialize node atop the query plan if needed.)
+ *
+ * Case #1 is converted to #2 or #3 by looking at the query itself and
+ * determining if scrollability can be supported without additional
+ * overhead.
+ *
+ * Protocol-level portals have no nonsequential-fetch API and so the
+ * distinction doesn't matter for them.  They are always initialized
+ * to look like NO SCROLL cursors.

+ * We have several execution strategies for Portals, depending on what

+ * executes just a single source-SQL query, and thus produces just a
+ * single result from the user's viewpoint.  However, the rule rewriter
+ * may expand the single source query to zero or many actual queries.)
+ *
+ * PORTAL_ONE_SELECT: the portal contains one single SELECT query.  We run
+ * the Executor incrementally as results are demanded.  This strategy also
+ * supports holdable cursors (the Executor results can be dumped into a
+ * tuplestore for access after transaction completion).
+ *
+ * PORTAL_ONE_RETURNING: the portal contains a single INSERT/UPDATE/DELETE
+ * query with a RETURNING clause (plus possibly auxiliary queries added by
+ * rule rewriting).  On first execution, we run the portal to completion
+ * and dump the primary query's results into the portal tuplestore; the
+ * results are then returned to the client as demanded.  (We can't support
+ * suspension of the query partway through, because the AFTER TRIGGER code
+ * can't cope, and also because we don't want to risk failing to execute
+ * all the auxiliary queries.)
+ *
+ * PORTAL_ONE_MOD_WITH: the portal contains one single SELECT query, but
+ * it has data-modifying CTEs.  This is currently treated the same as the
+ * PORTAL_ONE_RETURNING case because of the possibility of needing to fire
+ * triggers.  It may act more like PORTAL_ONE_SELECT in future.
+ *
+ * PORTAL_UTIL_SELECT: the portal contains a utility statement that returns
+ * a SELECT-like result (for example, EXPLAIN or SHOW).  On first execution,
+ * we run the statement and dump its results into the portal tuplestore;
+ * the results are then returned to the client as demanded.

+ *	  Framework for accelerated sorting.
+ *
+ * Traditionally, PostgreSQL has implemented sorting by repeatedly invoking
+ * an SQL-callable comparison function "cmp(x, y) returns int" on pairs of
+ * values to be compared, where the comparison function is the BTORDER_PROC
+ * pg_amproc support function of the appropriate btree index opclass.
+ *
+ * This file defines alternative APIs that allow sorting to be performed with
+ * reduced overhead.  To support lower-overhead sorting, a btree opclass may
+ * provide a BTSORTSUPPORT_PROC pg_amproc entry, which must take a single
+ * argument of type internal and return void.  The argument is actually a
+ * pointer to a SortSupportData struct, which is defined below.
+ *
+ * If provided, the BTSORTSUPPORT function will be called during sort setup,
+ * and it must initialize the provided struct with pointers to function(s)
+ * that can be called to perform sorting.  This API is defined to allow
+ * multiple acceleration mechanisms to be supported, but no opclass is
+ * required to provide all of them.  The BTSORTSUPPORT function should
+ * simply not set any function pointers for mechanisms it doesn't support.
+ * Opclasses that provide BTSORTSUPPORT and don't provide a comparator
+ * function will have a shim set up by sort support automatically.  However,
+ * opclasses that support the optional additional abbreviated key capability
+ * must always provide an authoritative comparator used to tie-break
+ * inconclusive abbreviated comparisons and also used when aborting
+ * abbreviation.  Furthermore, a converter and abort/costing function must be
+ * provided.
+ *
+ * All sort support functions will be passed the address of the
+ * SortSupportData struct when called, so they can use it to store
+ * additional private data as needed.  In particular, for collation-aware
+ * datatypes, the ssup_collation field is set before calling BTSORTSUPPORT
+ * and is available to all support functions.  Additional opclass-dependent
+ * data can be stored using the ssup_extra field.  Any such data
+ * should be allocated in the ssup_cxt memory context.
+ *
+ * Note: since pg_amproc functions are indexed by (lefttype, righttype)
+ * it is possible to associate a BTSORTSUPPORT function with a cross-type
+ * comparison.  This could sensibly be used to provide a fast comparator
+ * function for such cases, but probably not any other acceleration method.

+ * We provide multiple interfaces to what is essentially the same code,
+ * since different callers have different data to be sorted and want to
+ * specify the sort key information differently.  There are two APIs for
+ * sorting HeapTuples and two more for sorting IndexTuples.  Yet another
+ * API supports sorting bare Datums.
+ *
+ * Serial sort callers should pass NULL for their coordinate argument.
+ *
+ * The "heap" API actually stores/sorts MinimalTuples, which means it doesn't
+ * preserve the system columns (tuple identity and transaction visibility
+ * info).  The sort keys are specified by column numbers within the tuples
+ * and sort operator OIDs.  We save some cycles by passing and returning the
+ * tuples in TupleTableSlots, rather than forming actual HeapTuples (which'd
+ * have to be converted to MinimalTuples).  This API works well for sorts
+ * executed as parts of plan trees.
+ *
+ * The "cluster" API stores/sorts full HeapTuples including all visibility
+ * info. The sort keys are specified by reference to a btree index that is
+ * defined on the relation to be sorted.  Note that putheaptuple/getheaptuple
+ * go with this API, not the "begin_heap" one!
+ *
+ * The "index_btree" API stores/sorts IndexTuples (preserving all their
+ * header fields).  The sort keys are specified by a btree index definition.
+ *
+ * The "index_hash" API is similar to index_btree, but the tuples are
+ * actually sorted by their hash codes not the raw data.
+ *
+ * Parallel sort callers are required to coordinate multiple tuplesort states
+ * in a leader process and one or more worker processes.  The leader process
+ * must launch workers, and have each perform an independent "partial"
+ * tuplesort, typically fed by the parallel heap interface.  The leader later
+ * produces the final output (internally, it merges runs output by workers).
+ *
+ * Callers must do the following to perform a sort in parallel using multiple
+ * worker processes:
+ *
+ * 1. Request tuplesort-private shared memory for n workers.  Use
+ *    tuplesort_estimate_shared() to get the required size.
+ * 2. Have leader process initialize allocated shared memory using
+ *    tuplesort_initialize_shared().  Launch workers.
+ * 3. Initialize a coordinate argument within both the leader process, and
+ *    for each worker process.  This has a pointer to the shared
+ *    tuplesort-private structure, as well as some caller-initialized fields.
+ *    Leader's coordinate argument reliably indicates number of workers
+ *    launched (this is unused by workers).
+ * 4. Begin a tuplesort using some appropriate tuplesort_begin* routine,
+ *    (passing the coordinate argument) within each worker.  The workMem
+ *    arguments need not be identical.  All other arguments should match
+ *    exactly, though.
+ * 5. tuplesort_attach_shared() should be called by all workers.  Feed tuples
+ *    to each worker, and call tuplesort_performsort() within each when input
+ *    is exhausted.
+ * 6. Call tuplesort_end() in each worker process.  Worker processes can shut
+ *    down once tuplesort_end() returns.
+ * 7. Begin a tuplesort in the leader using the same tuplesort_begin*
+ *    routine, passing a leader-appropriate coordinate argument (this can
+ *    happen as early as during step 3, actually, since we only need to know
+ *    the number of workers successfully launched).  The leader must now wait
+ *    for workers to finish.  Caller must use own mechanism for ensuring that
+ *    next step isn't reached until all workers have called and returned from
+ *    tuplesort_performsort().  (Note that it's okay if workers have already
+ *    also called tuplesort_end() by then.)
+ * 8. Call tuplesort_performsort() in leader.  Consume output using the
+ *    appropriate tuplesort_get* routine.  Leader can skip this step if
+ *    tuplesort turns out to be unnecessary.
+ * 9. Call tuplesort_end() in leader.
+ *
+ * This division of labor assumes nothing about how input tuples are produced,
+ * but does require that caller combine the state of multiple tuplesorts for
+ * any purpose other than producing the final output.  For example, callers
+ * must consider that tuplesort_get_stats() reports on only one worker's role
+ * in a sort (or the leader's role), and not statistics for the sort as a
+ * whole.
+ *
+ * Note that callers may use the leader process to sort runs as if it was an
+ * independent worker process (prior to the process performing a leader sort
+ * to produce the final sorted output).  Doing so only requires a second
+ * "partial" tuplesort within the leader process, initialized like that of a
+ * worker process.  The steps above don't touch on this directly.  The only
+ * difference is that the tuplesort_attach_shared() call is never needed within
+ * leader process, because the backend as a whole holds the shared fileset
+ * reference.  A worker Tuplesortstate in leader is expected to do exactly the
+ * same amount of total initial processing work as a worker process
+ * Tuplesortstate, since the leader process has nothing else to do before
+ * workers finish.
+ *
+ * Note that only a very small amount of memory will be allocated prior to
+ * the leader state first consuming input, and that workers will free the
+ * vast majority of their memory upon returning from tuplesort_performsort().
+ * Callers can rely on this to arrange for memory to be used in a way that
+ * respects a workMem-style budget across an entire parallel sort operation.
+ *
+ * Callers are responsible for parallel safety in general.  However, they
+ * can at least rely on there being no parallel safety hazards within
+ * tuplesort, because tuplesort thinks of the sort as several independent
+ * sorts whose results are combined.  Since, in general, the behavior of
+ * sort operators is immutable, caller need only worry about the parallel
+ * safety of whatever the process is through which input tuples are
+ * generated (typically, caller uses a parallel heap scan).

+ * a dumbed-down version of tuplesort.c; it does no sorting of tuples
+ * but can only store and regurgitate a sequence of tuples.  However,

+ * a query without having to process the underlying scan to completion.
+ * Also, it is possible to support multiple independent read pointers.
+ *
+ * A temporary file is used to handle the data if it exceeds the
+ * space limit specified by the caller.
+ *
+ * Beginning in Postgres 8.2, what is stored is just MinimalTuples;
+ * callers cannot expect valid system columns in regurgitated tuples.
+ * Also, we have changed the API to return tuples in TupleTableSlots,
