+PostgreSQL tests
+================
+
+This directory contains a variety of test infrastructure as well as some of the
+tests in PostgreSQL. Not all tests are here -- in particular, there are more in
+individual contrib/ modules and in src/bin.
+
+Not all these tests get run by "make check". Check src/test/Makefile to see
+which tests get run automatically.
+
+authentication/
+  Tests for authentication (but see also below)
+
+examples/
+  Demonstration programs for libpq that double as regression tests via
+  "make check"
+
+isolation/
+  Tests for concurrent behavior at the SQL level
+
+kerberos/
+  Tests for Kerberos/GSSAPI authentication and encryption
+

+Regression tests for authentication
+===================================
+
+This directory contains a test suite for authentication. SSL certificate
+authentication tests are kept separate, in src/test/ssl/, because they
+are more complicated, and are not safe to run in a multi-user system.
+
+
+Running the tests
+=================
+
+NOTE: You must have given the --enable-tap-tests argument to configure.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install".
+In that case, the code in the installation tree is tested.  With
+"make check", a temporary installation tree is built from the current
+sources and then tested.
+
+Either way, this test initializes, starts, and stops a test Postgres
+cluster.

+Isolation tests
+===============
+
+This directory contains a set of tests for concurrent behaviors in
+PostgreSQL.  These tests require running multiple interacting transactions,
+which requires management of multiple concurrent connections, and therefore
+can't be tested using the normal pg_regress program.  The name "isolation"
+comes from the fact that the original motivation was to test the
+serializable isolation level; but tests for other sorts of concurrent
+behaviors have been added as well.
+
+You can run the tests against the current build tree by typing
+    make check
+Alternatively, you can run against an existing installation by typing
+    make installcheck
+(This will contact a server at the default port expected by libpq.
+You can set PGPORT and so forth in your environment to control this.)
+
+To run just specific test(s) against an installed server,
+you can do something like
+    ./pg_isolation_regress fk-contention fk-deadlock
+(look into the specs/ subdirectory to see the available tests).
+
+Certain tests require the server's max_prepared_transactions parameter to be
+set to at least 3; therefore they are not run by default.  To include them in
+the test run, use
+    make check-prepared-txns
+or
+    make installcheck-prepared-txns
+after making sure the server configuration is correct (see TEMP_CONFIG
+to adjust this in the "check" case).
+
+To define tests with overlapping transactions, we use test specification
+files with a custom syntax, which is described in the next section.  To add
+a new test, place a spec file in the specs/ subdirectory, add the expected
+output in the expected/ subdirectory, and add the test's name to the
+isolation_schedule file.
+
+isolationtester is a program that uses libpq to open multiple connections,
+and executes a test specified by a spec file. A libpq connection string
+specifies the server and database to connect to; defaults derived from
+environment variables are used otherwise.
+
+pg_isolation_regress is a tool similar to pg_regress, but instead of using
+psql to execute a test, it uses isolationtester.  It accepts all the same
+command-line arguments as pg_regress.
+
+By default, isolationtester will wait at most 300 seconds (5 minutes)
+for any one test step to complete.  If you need to adjust this, set
+the environment variable PGISOLATIONTIMEOUT to the desired timeout
+in seconds.
+
+
+Test specification
+==================
+
+Each isolation test is defined by a specification file, stored in the specs
+subdirectory.  A test specification defines some SQL "steps", groups them
+into "sessions" (where all the steps of one session will be run in the
+same backend), and specifies the "permutations" or orderings of the steps
+that are to be run.
+
+A test specification consists of four parts, in this order:
+
+setup { <SQL> }
+
+  The given SQL block is executed once (per permutation) before running
+  the test.  Create any test tables or other required objects here.  This
+  part is optional.  Multiple setup blocks are allowed if needed; each is
+  run separately, in the given order.  (The reason for allowing multiple
+  setup blocks is that each block is run as a single PQexec submission,
+  and some statements such as VACUUM cannot be combined with others in such
+  a block.)
+
+teardown { <SQL> }
+
+  The teardown SQL block is executed once after the test is finished. Use
+  this to clean up in preparation for the next permutation, e.g dropping
+  any test tables created by setup. This part is optional.
+
+session <name>
+
+  There are normally several "session" parts in a spec file. Each
+  session is executed in its own connection. A session part consists
+  of three parts: setup, teardown and one or more "steps". The per-session
+  setup and teardown parts have the same syntax as the per-test setup and
+  teardown described above, but they are executed in each session. The setup
+  part might, for example, contain a "BEGIN" command to begin a transaction.
+
+  Each step has the syntax
+
+  step <name> { <SQL> }
+
+  where <name> is a name identifying this step, and <SQL> is a SQL statement
+  (or statements, separated by semicolons) that is executed in the step.
+  Step names must be unique across the whole spec file.
+
+permutation <step name> ...
+
+  A permutation line specifies a list of steps that are run in that order.
+  Any number of permutation lines can appear.  If no permutation lines are
+  given, the test program automatically runs all possible interleavings
+  of the steps from each session (running the steps of any one session in
+  order).  Note that the list of steps in a manually specified
+  "permutation" line doesn't actually have to be a permutation of the
+  available steps; it could for instance repeat some steps more than once,
+  or leave others out.  Also, each step name can be annotated with some
+  parenthesized markers, which are described below.
+
+Session and step names are SQL identifiers, either plain or double-quoted.
+A difference from standard SQL is that no case-folding occurs, so that
+FOO and "FOO" are the same name while FOO and Foo are different,
+whether you quote them or not.  You must use quotes if you want to use
+an isolation test keyword (such as "permutation") as a name.
+
+A # character begins a comment, which extends to the end of the line.
+(This does not work inside <SQL> blocks, however.  Use the usual SQL
+comment conventions there.)
+
+There is no way to include a "}" character in an <SQL> block.
+
+For each permutation of the session steps (whether these are manually
+specified in the spec file, or automatically generated), the isolation
+tester runs the main setup part, then per-session setup parts, then
+the selected session steps, then per-session teardown, then the main
+teardown script.  Each selected step is sent to the connection associated
+with its session.  The main setup and teardown scripts are run in a
+separate "control" session.
+
+
+Support for blocking commands
+=============================
+
+Each step may contain commands that block until further action has been taken
+(most likely, some other session runs a step that unblocks it or causes a
+deadlock).  A test that uses this ability must manually specify valid
+permutations, i.e. those that would not expect a blocked session to execute a
+command.  If a test fails to follow that rule, isolationtester will cancel it
+after PGISOLATIONTIMEOUT seconds.  If the cancel doesn't work, isolationtester
+will exit uncleanly after a total of twice PGISOLATIONTIMEOUT.  Testing
+invalid permutations should be avoided because they can make the isolation
+tests take a very long time to run, and they serve no useful testing purpose.
+
+Note that isolationtester recognizes that a command has blocked by looking
+to see if it is shown as waiting in the pg_locks view; therefore, only
+blocks on heavyweight locks will be detected.
+
+
+Dealing with race conditions
+============================
+
+In some cases, the isolationtester's output for a test script may vary
+due to timing issues.  One way to deal with that is to create variant
+expected-files, which follow the usual PG convention that variants for
+foo.spec are named foo_1.out, foo_2.out, etc.  However, this method is
+discouraged since the extra files are a nuisance for maintenance.
+Instead, it's usually possible to stabilize the test output by applying
+special markers to some of the step names listed in a permutation line.
+
+The general form of a permutation entry is
+
+	<step name> [ ( <marker> [ , <marker> ... ] ) ]
+
+where each marker defines a "blocking condition".  The step will not be
+reported as completed before all the blocking conditions are satisfied.
+The possible markers are:
+
+	*
+	<other step name>
+	<other step name> notices <n>
+
+An asterisk marker, such as mystep(*), forces the isolationtester to
+report the step as "waiting" as soon as it's been launched, regardless of
+whether it would have been detected as waiting later.  This is useful for
+stabilizing cases that are sometimes reported as waiting and other times
+reported as immediately completing, depending on the relative speeds of
+the step and the isolationtester's status-monitoring queries.
+
+A marker consisting solely of a step name indicates that this step may
+not be reported as completing until that other step has completed.
+This allows stabilizing cases where two queries might be seen to complete
+in either order.  Note that this step can be *launched* before the other
+step has completed.  (If the other step is used more than once in the
+current permutation, this step cannot complete while any of those
+instances is active.)
+
+A marker of the form "<other step name> notices <n>" (where <n> is a
+positive integer) indicates that this step may not be reported as
+completing until the other step's session has returned at least <n>
+NOTICE messages, counting from when this step is launched.  This is useful
+for stabilizing cases where a step can return NOTICE messages before it
+actually completes, and those messages must be synchronized with the
+completions of other steps.
+
+Notice that these markers can only delay reporting of the completion
+of a step, not the launch of a step.  The isolationtester will launch
+the next step in a permutation as soon as (A) all prior steps of the
+same session are done, and (B) the immediately preceding step in the
+permutation is done or deemed blocked.  For this purpose, "deemed
+blocked" means that it has been seen to be waiting on a database lock,
+or that it is complete but the report of its completion is delayed by
+one of these markers.
+
+In some cases it is important not to launch a step until after the
+completion of a step in another session that could have been deemed
+blocked.  An example is that if step s1 in session A is issuing a
+cancel for step s2 in session B, we'd better not launch B's next step
+till we're sure s1 is done.  If s1 is blockable, trouble could ensue.
+The best way to prevent that is to create an empty step in session A
+and run it, without any markers, just before the next session B step.
+The empty step cannot be launched until s1 is done, and in turn the
+next session B step cannot be launched until the empty step finishes.

+# Test deadlock resolution with parallel process groups.
+
+# It's fairly hard to get parallel worker processes to block on locks,
+# since generally they don't want any locks their leader didn't already
+# take.  We cheat like mad here by making a function that takes a lock,
+# and is incorrectly marked parallel-safe so that it can execute in a worker.
+
+# Note that we explicitly override any global settings of isolation level
+# or force_parallel_mode, to ensure we're testing what we intend to.
+
+# Otherwise, this is morally equivalent to deadlock-soft.spec:
+# Four-process deadlock with two hard edges and two soft edges.
+# d2 waits for e1 (soft edge), e1 waits for d1 (hard edge),
+# d1 waits for e2 (soft edge), e2 waits for d2 (hard edge).
+# The deadlock detector resolves the deadlock by reversing the d1-e2 edge,
+# unblocking d1.
+
+# However ... it's not actually that well-defined whether the deadlock
+# detector will prefer to unblock d1 or d2.  It depends on which backend
+# is first to run DeadLockCheck after the deadlock condition is created:
+# that backend will search outwards from its own wait condition, and will
+# first find a loop involving the *other* lock.  We encourage that to be
+# one of the d2a1 parallel workers, which will therefore unblock d1a2
+# workers, by setting a shorter deadlock_timeout in session d2.  But on
+# slow machines, one or more d1a2 workers may not yet have reached their
+# lock waits, so that they're not unblocked by the first DeadLockCheck.
+# The next DeadLockCheck may choose to unblock the d2a1 workers instead,
+# which would allow d2a1 to complete before d1a2, causing the test to
+# freeze up because isolationtester isn't expecting that completion order.
+# (In effect, we have an undetectable deadlock because d2 is waiting for
+# d1's completion, but on the client side.)  To fix this, introduce an
+# additional lock (advisory lock 3), which is initially taken by d1 and
+# then d2a1 will wait for it after completing the main part of the test.
+# In this way, the deadlock detector can see that d1 must be completed
+# first, regardless of timing.

+# INSERT...ON CONFLICT DO UPDATE test
+#
+# Other INSERT...ON CONFLICT DO UPDATE isolation tests illustrate the "MVCC
+# violation" added to facilitate the feature, whereby a
+# not-visible-to-our-snapshot tuple can be updated by our command all the same.
+# This is generally needed to provide a guarantee of a successful INSERT or
+# UPDATE in READ COMMITTED mode.  This MVCC violation is quite distinct from
+# the putative "MVCC violation" that has existed in PostgreSQL for many years,
+# the EvalPlanQual() mechanism, because that mechanism always starts from a
+# tuple that is visible to the command's MVCC snapshot.  This test illustrates
+# a slightly distinct user-visible consequence of the same MVCC violation
+# generally associated with INSERT...ON CONFLICT DO UPDATE.  The impact of the
+# MVCC violation goes a little beyond updating MVCC-invisible tuples.
+#
+# With INSERT...ON CONFLICT DO UPDATE, the UPDATE predicate is only evaluated
+# once, on this conclusively-locked tuple, and not any other version of the
+# same tuple.  It is therefore possible (in READ COMMITTED mode) that the
+# predicate "fail to be satisfied" according to the command's MVCC snapshot.
+# It might simply be that there is no row version visible, but it's also
+# possible that there is some row version visible, but only as a version that
+# doesn't satisfy the predicate.  If, however, the conclusively-locked version
+# satisfies the predicate, that's good enough, and the tuple is updated.  The
+# MVCC-snapshot-visible row version is denied the opportunity to prevent the
+# UPDATE from taking place, because we don't walk the UPDATE chain in the usual

+# To bring the number of permutations down a bit, we further require
+# them to satisfy *one* of the following:
+#  - r1 < w2 < r2 < w3   (T1-->T2 conflict on write, T2-->T3 on write)
+#  - r1 < w2 < w3 < r2   (T1-->T2 conflict on read, T2-->T3 on write)

+#  - w2 < r1 < w3 < r2   (T1-->T2 conflict on read, T2-->T3 on read)
+# This eliminates some redundant combinations. For example, it doesn't
+# matter if w2 happens before w3 as long as both come before the
+# conflicting reads.

+Tests for Kerberos/GSSAPI functionality
+=======================================
+
+This directory contains a test suite for Kerberos/GSSAPI
+functionality.  This requires a full MIT Kerberos installation,
+including server and client tools, and is therefore kept separate and
+not run by default.
+
+CAUTION: The test server run by this test is configured to listen for TCP
+connections on localhost. Any user on the same host is able to log in to the
+test server while the tests are running. Do not run this suite on a multi-user
+system where you don't trust all local users! Also, this test suite creates a
+KDC server that listens for TCP/IP connections on localhost without any real
+access control.
+
+Running the tests
+=================
+
+NOTE: You must have given the --enable-tap-tests argument to configure.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install".
+In that case, the code in the installation tree is tested.  With
+"make check", a temporary installation tree is built from the current
+sources and then tested.
+
+Either way, this test initializes, starts, and stops a test Postgres
+cluster, as well as a test KDC server.
+
+Requirements
+============
+
+MIT Kerberos server and client tools are required.  Heimdal is not
+supported.
+
+Debian/Ubuntu packages: krb5-admin-server krb5-kdc krb5-user
+
+RHEL/CentOS/Fedora packages: krb5-server krb5-workstation
+
+FreeBSD port: krb5 (base system has Heimdal)

+Tests for LDAP functionality
+============================
+
+This directory contains a test suite for LDAP functionality.  This
+requires a full OpenLDAP installation, including server and client
+tools, and is therefore kept separate and not run by default.  You
+might need to adjust some paths in the test file to have it find
+OpenLDAP in a place that hadn't been thought of yet.
+
+Also, this test suite creates an LDAP server that listens for TCP/IP
+connections on localhost without any real access control, so it is not
+safe to run this on a system where there might be untrusted local
+users.
+
+Running the tests
+=================
+
+NOTE: You must have given the --enable-tap-tests argument to configure.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install".
+In that case, the code in the installation tree is tested.  With
+"make check", a temporary installation tree is built from the current
+sources and then tested.
+
+Either way, this test initializes, starts, and stops a test Postgres
+cluster, as well as a test LDAP server.
+
+Requirements
+============
+
+LDAP server and client tools are required.
+
+Debian/Ubuntu packages: slapd ldap-utils
+
+RHEL/CentOS/Fedora packages: openldap-clients openldap-servers
+(You will already have needed openldap and openldap-devel to build.)
+
+FreeBSD: openldap-server
+(You will already have needed openldap-client to build.  If building
+from the ports source tree, you want to build net/openldap24-client
+and net/openldap24-server.)
+
+macOS: We do not recommend trying to use the Apple-provided version of
+OpenLDAP; it's very old, plus Apple seem to have changed the launching
+conventions for slapd.  The paths in the test file are set on the
+assumption that you installed OpenLDAP using Homebrew or MacPorts.

+Locales
+=======
+
+This directory contains a set of tests for locales.  I provided one C
+program test-ctype.c to test CTYPE support in libc and the installed
+locale data.  Then there are test-sort.pl and test-sort.py that test
+collating.
+
+To run a test for some locale run
+    make check-$locale
+for example
+    make check-koi8-r
+
+Currently, there are only tests for a few locales available.  The script
+'runall' calls test-ctype to test libc and locale data, test-sort.pl
+(uncomment test-sort.py, if you have a Python interpreter installed), and
+does tests on PostgreSQL with the provided SQL script files.
+
+To add locale tests one needs to create a directory $locale and create
+a Makefile (and other files) similar to koi8-r/*.  Actually, the simplest
+(I think) method is just to copy the koi8-r directory and edit/replace
+the files.
+
+Oleg.

+Test extensions and libraries
+=============================
+
+src/test/modules contains PostgreSQL extensions that are primarily or entirely
+intended for testing PostgreSQL and/or to serve as example code. The extensions
+here aren't intended to be installed in a production server and aren't suitable
+for "real work".
+
+Furthermore, while you can do "make install" and "make installcheck" in
+this directory or its children, it is NOT ADVISABLE to do so with a server
+containing valuable data.  Some of these tests may have undesirable
+side-effects on roles or other global objects within the tested server.
+"make installcheck-world" at the top level does not recurse into this
+directory.
+
+Most extensions have their own pg_regress tests or isolationtester specs. Some
+are also used by tests elsewhere in the tree.
+
+If you're adding new hooks or other functionality exposed as C-level API this
+is where to add the tests for it.

+Dummy index AM is a module for testing any facility usable by an index
+access method, whose code is kept a maximum simple.
+
+This includes tests for all relation option types:
+- boolean
+- enum
+- integer
+- real
+- strings (with and without NULL as default)

+The dummy_seclabel module exists only to support regression testing of
+the SECURITY LABEL statement.  It is not intended to be used in production.
+
+Rationale
+=========
+
+The SECURITY LABEL statement allows the user to assign security labels to
+database objects; however, security labels can only be assigned when
+specifically allowed by a loadable module, so this module is provided to
+allow proper regression testing.
+
+Security label providers intended to be used in production will typically be
+dependent on a platform-specific feature such as SELinux.  This module is
+platform-independent, and therefore better-suited to regression testing.
+
+Usage
+=====
+
+Here's a simple example of usage:
+
+# postgresql.conf
+shared_preload_libraries = 'dummy_seclabel'
+
+postgres=# CREATE TABLE t (a int, b text);
+CREATE TABLE
+postgres=# SECURITY LABEL ON TABLE t IS 'classified';
+SECURITY LABEL
+
+The dummy_seclabel module provides only four hardcoded
+labels: unclassified, classified,
+secret, and top secret.
+It does not allow any other strings as security labels.
+
+These labels are not used to enforce access controls.  They are only used
+to check whether the SECURITY LABEL statement works as expected,
+or not.

+test_bloomfilter overview
+=========================
+
+test_bloomfilter is a test harness module for testing Bloom filter library set
+membership operations.  It consists of a single SQL-callable function,
+test_bloomfilter(), plus a regression test that calls test_bloomfilter().
+Membership tests are performed against a dataset that the test harness module
+generates.
+
+The test_bloomfilter() function displays instrumentation at DEBUG1 elog level
+(WARNING when the false positive rate exceeds a 1% threshold).  This can be
+used to get a sense of the performance characteristics of the Postgres Bloom
+filter implementation under varied conditions.
+
+Bitset size
+-----------
+
+The main bloomfilter.c criteria for sizing its bitset is that the false
+positive rate should not exceed 2% when sufficient bloom_work_mem is available
+(and the caller-supplied estimate of the number of elements turns out to have
+been accurate).  A 1% - 2% rate is currently assumed to be suitable for all
+Bloom filter callers.
+
+With an optimal K (number of hash functions), Bloom filters should only have a
+1% false positive rate with just 9.6 bits of memory per element.  The Postgres
+implementation's 2% worst case guarantee exists because there is a need for
+some slop due to implementation inflexibility in bitset sizing.  Since the
+bitset size is always actually kept to a power of two number of bits, callers
+can have their bloom_work_mem argument truncated down by almost half.
+In practice, callers that make a point of passing a bloom_work_mem that is an
+exact power of two bitset size (such as test_bloomfilter.c) will actually get
+the "9.6 bits per element" 1% false positive rate.
+
+Testing strategy
+----------------
+
+Our approach to regression testing is to test that a Bloom filter has only a 1%
+false positive rate for a single bitset size (2 ^ 23, or 1MB).  We test a
+dataset with 838,861 elements, which works out at 10 bits of memory per
+element.  We round up from 9.6 bits to 10 bits to make sure that we reliably
+get under 1% for regression testing.  Note that a random seed is used in the
+regression tests because the exact false positive rate is inconsistent across
+platforms.  Inconsistent hash function behavior is something that the
+regression tests need to be tolerant of anyway.
+
+test_bloomfilter() SQL-callable function
+========================================
+
+The SQL-callable function test_bloomfilter() provides the following arguments:
+
+* "power" is the power of two used to size the Bloom filter's bitset.
+
+The minimum valid argument value is 23 (2^23 bits), or 1MB of memory.  The
+maximum valid argument value is 32, or 512MB of memory.
+
+* "nelements" is the number of elements to generate for testing purposes.
+
+* "seed" is a seed value for hashing.
+
+A value < 0 is interpreted as "use random seed".  Varying the seed value (or
+specifying -1) should result in small variations in the total number of false
+positives.
+
+* "tests" is the number of tests to run.
+
+This may be increased when it's useful to perform many tests in an interactive
+session.  It only makes sense to perform multiple tests when a random seed is
+used.

+test_ddl_deparse is an example of how to use the pg_ddl_command datatype.
+It is not intended to do anything useful on its own; rather, it is a
+demonstration of how to use the datatype, and to provide some unit tests for
+it.
+
+The functions in this extension are intended to be able to process some
+part of the struct and produce some readable output, preferably handling
+all possible cases so that SQL test code can be written.

+test_parser is an example of a custom parser for full-text
+search.  It doesn't do anything especially useful, but can serve as
+a starting point for developing your own parser.
+
+test_parser recognizes words separated by white space,
+and returns just two token types:
+
+mydb=# SELECT * FROM ts_token_type('testparser');
+ tokid | alias |  description
+-------+-------+---------------
+     3 | word  | Word
+    12 | blank | Space symbols
+(2 rows)
+
+These token numbers have been chosen to be compatible with the default
+parser's numbering.  This allows us to use its headline()
+function, thus keeping the example simple.
+
+Usage
+=====
+
+Installing the test_parser extension creates a text search
+parser testparser.  It has no user-configurable parameters.
+
+You can test the parser with, for example,
+
+mydb=# SELECT * FROM ts_parse('testparser', 'That''s my first own parser');
+ tokid | token
+-------+--------
+     3 | That's
+    12 |
+     3 | my
+    12 |
+     3 | first
+    12 |
+     3 | own
+    12 |
+     3 | parser
+
+Real-world use requires setting up a text search configuration
+that uses the parser.  For example,
+
+mydb=# CREATE TEXT SEARCH CONFIGURATION testcfg ( PARSER = testparser );
+CREATE TEXT SEARCH CONFIGURATION
+
+mydb=# ALTER TEXT SEARCH CONFIGURATION testcfg
+mydb-#   ADD MAPPING FOR word WITH english_stem;
+ALTER TEXT SEARCH CONFIGURATION
+
+mydb=#  SELECT to_tsvector('testcfg', 'That''s my first own parser');
+          to_tsvector
+-------------------------------
+ 'that':1 'first':3 'parser':5
+(1 row)
+
+mydb=# SELECT ts_headline('testcfg', 'Supernovae stars are the brightest phenomena in galaxies',
+mydb(#                    to_tsquery('testcfg', 'star'));
+                           ts_headline
+-----------------------------------------------------------------
+ Supernovae <b>stars</b> are the brightest phenomena in galaxies

+# Definition of the tests to run.
+#
+# Each test is defined using the log message that will be used.
+#
+# A regexp should be defined for each test which provides the
+# basis for the test.  That regexp will be run against the output
+# file of each of the runs which the test is to be run against
+# and the success of the result will depend on if the regexp
+# result matches the expected 'like' or 'unlike' case.
+# The runs listed as 'like' will be checked if they match the
+# regexp and, if so, the test passes.  All runs which are not
+# listed as 'like' will be checked to ensure they don't match
+# the regexp; if they do, the test will fail.
+#
+# The below hashes provide convenience sets of runs.  Individual
+# runs can be excluded from a general hash by placing that run
+# into the 'unlike' section.
+#
+# There can then be a 'create_sql' and 'create_order' for a
+# given test.  The 'create_sql' commands are collected up in
+# 'create_order' and then run against the database prior to any
+# of the pg_dump runs happening.  This is what "seeds" the
+# system with objects to be dumped out.
+#
+# Building of this hash takes a bit of time as all of the regexps
+# included in it are compiled.  This greatly improves performance
+# as the regexps are used for each run the test applies to.

+test_predtest is a module for checking the correctness of the optimizer's
+predicate-proof logic, in src/backend/optimizer/util/predtest.c.
+
+The module provides a function that allows direct application of
+predtest.c's exposed functions, predicate_implied_by() and
+predicate_refuted_by(), to arbitrary boolean expressions, with direct
+inspection of the results.  This could be done indirectly by checking
+planner results, but it can be difficult to construct end-to-end test
+cases that prove that the expected results were obtained.
+
+In general, the use of this function is like
+	select * from test_predtest('query string')
+where the query string must be a SELECT returning two boolean
+columns, for example
+
+	select * from test_predtest($$
+	select x, not x
+	from (values (false), (true), (null)) as v(x)
+	$$);
+
+The function parses and plans the given query, and then applies the
+predtest.c code to the two boolean expressions in the SELECT list, to see
+if the first expression can be proven or refuted by the second.  It also
+executes the query, and checks the resulting rows to see whether any
+claimed implication or refutation relationship actually holds.  If the
+query is designed to exercise the expressions on a full set of possible
+input values, as in the example above, then this provides a mechanical
+cross-check as to whether the proof code has given a correct answer.

+test_rbtree is a test module for checking the correctness of red-black
+tree operations.
+
+These tests are performed on red-black trees that store integers.
+Since the rbtree logic treats the comparison function as a black
+box, it shouldn't be important exactly what the key type is.
+
+Checking the correctness of traversals is based on the fact that a red-black
+tree is a binary search tree, so the elements should be visited in increasing
+(for Left-Current-Right) or decreasing (for Right-Current-Left) order.
+
+Also, this module does some checks of the correctness of the find, delete
+and leftmost operations.

+test_regex is a module for testing the regular expression package.
+It is mostly meant to allow us to absorb Tcl's regex test suite.
+Therefore, there are provisions to exercise regex features that
+aren't currently exposed at the SQL level by PostgreSQL.
+
+Currently, one function is provided:
+
+test_regex(pattern text, string text, flags text) returns setof text[]
+
+Reports an error if the pattern is an invalid regex.  Otherwise,
+the first row of output contains the number of subexpressions,
+followed by words reporting set bit(s) in the regex's re_info field.
+If the pattern doesn't match the string, that's all.
+If the pattern does match, the next row contains the whole match
+as the first array element.  If there are parenthesized subexpression(s),
+following array elements contain the matches to those subexpressions.
+If the "g" (glob) flag is set, then additional row(s) of output similarly
+report any additional matches.
+
+The "flags" argument is a string of zero or more single-character
+flags that modify the behavior of the regex package or the test
+function.  As described in Tcl's reg.test file:
+
+The flag characters are complex and a bit eclectic.  Generally speaking,
+lowercase letters are compile options, uppercase are expected re_info
+bits, and nonalphabetics are match options, controls for how the test is
+run, or testing options.  The one small surprise is that AREs are the
+default, and you must explicitly request lesser flavors of RE.  The flags
+are as follows.  It is admitted that some are not very mnemonic.
+
+	-	no-op (placeholder)
+	0	report indices not actual strings
+		(This substitutes for Tcl's -indices switch)
+	!	expect partial match, report start position anyway
+	%	force small state-set cache in matcher (to test cache replace)
+	^	beginning of string is not beginning of line
+	$	end of string is not end of line
+	*	test is Unicode-specific, needs big character set
+	+	provide fake xy equivalence class and ch collating element
+		(Note: the equivalence class is implemented, the
+		collating element is not; so references to [.ch.] fail)
+	,	set REG_PROGRESS (only useful in REG_DEBUG builds)
+	.	set REG_DUMP (only useful in REG_DEBUG builds)
+	:	set REG_MTRACE (only useful in REG_DEBUG builds)
+	;	set REG_FTRACE (only useful in REG_DEBUG builds)
+
+	&	test as both ARE and BRE
+		(Not implemented in Postgres, we use separate tests)
+	b	BRE
+	e	ERE
+	a	turn advanced-features bit on (error unless ERE already)
+	q	literal string, no metacharacters at all
+
+	g	global match (find all matches)
+	i	case-independent matching
+	o	("opaque") do not return match locations
+	p	newlines are half-magic, excluded from . and [^ only
+	w	newlines are half-magic, significant to ^ and $ only
+	n	newlines are fully magic, both effects
+	x	expanded RE syntax
+	t	incomplete-match reporting
+	c	canmatch (equivalent to "t0!", in Postgres implementation)
+	s	match only at start (REG_BOSONLY)
+
+	A	backslash-_a_lphanumeric seen
+	B	ERE/ARE literal-_b_race heuristic used
+	E	backslash (_e_scape) seen within []
+	H	looka_h_ead constraint seen
+	I	_i_mpossible to match
+	L	_l_ocale-specific construct seen
+	M	unportable (_m_achine-specific) construct seen
+	N	RE can match empty (_n_ull) string
+	P	non-_P_OSIX construct seen
+	Q	{} _q_uantifier seen
+	R	back _r_eference seen
+	S	POSIX-un_s_pecified syntax seen

+test_shm_mq is an example of how to use dynamic shared memory
+and the shared memory message queue facilities to coordinate a user backend
+with the efforts of one or more background workers.  It is not intended to
+do anything useful on its own; rather, it is a demonstration of how these
+facilities can be used, and a unit test of those facilities.
+
+The function is this extension send the same message repeatedly through
+a loop of processes.  The message payload, the size of the message queue
+through which it is sent, and the number of processes in the loop are
+configurable.  At the end, the message may be verified to ensure that it
+has not been corrupted in transmission.
+
+Functions
+=========
+
+
+test_shm_mq(queue_size int8, message text,
+            repeat_count int4 default 1, num_workers int4 default 1)
+    RETURNS void
+
+This function sends and receives messages synchronously.  The user
+backend sends the provided message to the first background worker using
+a message queue of the given size.  The first background worker sends
+the message to the second background worker, if the number of workers
+is greater than one, and so forth.  Eventually, the last background
+worker sends the message back to the user backend.  If the repeat count
+is greater than one, the user backend then sends the message back to
+the first worker.  Once the message has been sent and received by all
+the coordinating processes a number of times equal to the repeat count,
+the user backend verifies that the message finally received matches the
+one originally sent and throws an error if not.
+
+
+test_shm_mq_pipelined(queue_size int8, message text,
+                      repeat_count int4 default 1, num_workers int4 default 1,
+                      verify bool default true)
+    RETURNS void
+
+This function sends the same message multiple times, as specified by the
+repeat count, to the first background worker using a queue of the given
+size.  These messages are then forwarded to each background worker in
+turn, in each case using a queue of the given size.  Finally, the last
+background worker sends the messages back to the user backend.  The user
+backend uses non-blocking sends and receives, so that it may begin receiving
+copies of the message before it has finished sending all copies of the
+message.  The 'verify' argument controls whether or not the
+received copies are checked against the message that was sent.  (This
+takes nontrivial time so it may be useful to disable it for benchmarking
+purposes.)

+=head1 DESCRIPTION
+
+PostgresNode contains a set of routines able to work on a PostgreSQL node,
+allowing to start, stop, backup and initialize it with various options.
+The set of nodes managed by a given test is also managed by this module.
+
+In addition to node management, PostgresNode instances have some wrappers
+around Test::More functions to run commands with an environment set up to
+point to the instance.
+
+The IPC::Run module is required.

+Perl-based TAP tests
+====================
+
+src/test/perl/ contains shared infrastructure that's used by Perl-based tests
+across the source tree, particularly tests in src/bin and src/test. It's used
+to drive tests for backup and restore, replication, etc - anything that can't
+really be expressed using pg_regress or the isolation test framework.
+
+The tests are invoked via perl's 'prove' command, wrapped in PostgreSQL
+makefiles to handle instance setup etc. See the $(prove_check) and
+$(prove_installcheck) targets in Makefile.global. By default every test in the
+t/ subdirectory is run. Individual test(s) can be run instead by passing
+something like PROVE_TESTS="t/001_testname.pl t/002_othertestname.pl" to make.
+
+You should prefer to write tests using pg_regress in src/test/regress, or
+isolation tester specs in src/test/isolation, if possible. If not, check to
+see if your new tests make sense under an existing tree in src/test, like
+src/test/ssl, or should be added to one of the suites for an existing utility.
+
+Note that all tests and test tools should have perltidy run on them before
+patches are submitted, using perltidy --profile=src/tools/pgindent/perltidyrc
+
+By default, to keep the noise low during runs, we do not set any flags via
+PROVE_FLAGS, but this can be done on the 'make' command line if desired, eg:
+
+make check-world PROVE_FLAGS='--verbose'
+
+Writing tests
+-------------
+
+Tests are written using Perl's Test::More with some PostgreSQL-specific
+infrastructure from src/test/perl providing node management, support for
+invoking 'psql' to run queries and get results, etc. You should read the
+documentation for Test::More before trying to write tests.
+
+Test scripts in the t/ subdirectory of a suite are executed in alphabetical
+order.
+
+Each test script should begin with:
+
+    use strict;
+    use warnings;
+    use PostgresNode;
+    use TestLib;
+    # Replace with the number of tests to execute:
+    use Test::More tests => 1;
+
+then it will generally need to set up one or more nodes, run commands
+against them and evaluate the results. For example:
+
+    my $node = PostgresNode->get_new_node('primary');
+    $node->init;
+    $node->start;
+
+    my $ret = $node->safe_psql('postgres', 'SELECT 1');
+    is($ret, '1', 'SELECT 1 returns 1');
+
+    $node->stop('fast');
+
+Test::More::like entails use of the qr// operator.  Avoid Perl 5.8.8 bug
+#39185 by not using the "$" regular expression metacharacter in qr// when also
+using the "/m" modifier.  Instead of "$", use "\n" or "(?=\n|\z)".
+
+Test::Builder::Level controls how far up in the call stack a test will look
+at when reporting a failure.  This should be incremented by any subroutine
+which directly or indirectly calls test routines from Test::More, such as
+ok() or is():
+
+    local $Test::Builder::Level = $Test::Builder::Level + 1;
+
+Read the documentation for more on how to write tests:
+
+    perldoc Test::More
+    perldoc Test::Builder
+
+For available PostgreSQL-specific test methods and some example tests read the
+perldoc for the test modules, e.g.:
+
+    perldoc src/test/perl/PostgresNode.pm
+
+Required Perl
+-------------
+
+Tests must run on perl 5.8.0 and newer. perlbrew is a good way to obtain such
+a Perl; see http://perlbrew.pl .
+
+Just install and
+
+    perlbrew --force install 5.8.0
+    perlbrew use 5.8.0
+    perlbrew install-cpanm
+    cpanm install IPC::Run
+
+then re-run configure to ensure the correct Perl is used when running
+tests. To verify that the right Perl was found:
+
+    grep ^PERL= config.log

+
+RecursiveCopy - simple recursive copy implementation
+
+=head1 SYNOPSIS

+RecursiveCopy::copypath($from, $to);

+=pod
+
+=head1 DESCRIPTION
+
+=head2 copypath($from, $to, %params)
+
+Recursively copy all files and directories from $from to $to.
+Does not preserve file metadata (e.g., permissions).
+
+Only regular files and subdirectories are copied.  Trying to copy other types
+of directory entries raises an exception.
+
+Raises an exception if a file would be overwritten, the source directory can't
+be read, or any I/O operation fails.  However, we silently ignore ENOENT on
+open, because when copying from a live database it's possible for a file/dir
+to be deleted after we see its directory entry but before we can open it.
+
+Always returns true.
+
+If the B<filterfn> parameter is given, it must be a subroutine reference.
+This subroutine will be called for each entry in the source directory with its
+relative path as only parameter; if the subroutine returns true the entry is
+copied, otherwise the file is skipped.
+
+On failure the target directory may be in some incomplete state; no cleanup is
+attempted.

+contrib/test_decoding in addition to the core code.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install".
+In that case, the code in the installation tree is tested.  With
+"make check", a temporary installation tree is built from the current
+sources and then tested.
+
+Either way, this test initializes, starts, and stops several test Postgres
+clusters.

+#
+# Logical replication slots can follow timeline switches but it's
+# normally not possible to have a logical slot on a replica where
+# promotion and a timeline switch can occur. The only ways
+# we can create that circumstance are:
+#
+# * By doing a filesystem-level copy of the DB, since pg_basebackup
+#   excludes pg_replslot but we can copy it directly; or
+#
+# * by creating a slot directly at the C level on the replica and
+#   advancing it as we go using the low level APIs. It can't be done
+#   from SQL since logical decoding isn't allowed on replicas.
+#
+# This module uses the first approach to show that timeline following
+# on a logical slot works.

+-- if its underlying btree operator family doesn't include a complete set
+-- of cross-type equality operators.  There are not (and should not be)
+-- any such families built into Postgres; so we have to hack things up
+-- to create one.  We do this by making two alias types that are really
+-- int8 (so we need no new C code) and adding only some operators for them

+-- Scenario:
+--
+--     A building with a modern TP cable installation where any
+--     of the wall connectors can be used to plug in phones,
+--     ethernet interfaces or local office hubs. The backside
+--     of the wall connectors is wired to one of several patch-
+--     fields in the building.
+--
+--     In the patchfields, there are hubs and all the slots
+--     representing the wall connectors. In addition there are
+--     slots that can represent a phone line from the central
+--     phone system.
+--
+--     Triggers ensure consistency of the patching information.
+--
+--     Functions are used to build up powerful views that let
+--     you look behind the wall when looking at a patchfield
+--     or into a room.

+-- Check that system tables can be reindexed.

+-- Note that this test currently is not included in the default
+-- schedules, as currently reindexing catalog tables can cause
+-- deadlocks:
+--
+-- * The lock upgrade between the ShareLock acquired for the reindex
+--   and RowExclusiveLock needed for pg_class/pg_index locks can
+--   trigger deadlocks.
+--
+-- * The uniqueness checks performed when reindexing a unique/primary
+--   key index possibly need to wait for the transaction of a
+--   about-to-deleted row in pg_class to commit. That can cause
+--   deadlocks because, in contrast to user tables, locks on catalog
+--   tables are routinely released before commit - therefore the lock
+--   held for reindexing doesn't guarantee that no running transaction
+--   performed modifications in the table underlying the index.
+--
+--   This is particularly problematic as such conflicts can be
+--   triggered even when run in isolation, as a previous session's

+Fluttering and dancing in the breeze.
+
+Continuous as the stars that shine
+And twinkle on the milky way,
+They stretched in never-ending line
+Along the margin of a bay:
+Ten thousand saw I at a glance,
+Tossing their heads in sprightly dance.
+
+The waves beside them danced; but they
+Out-did the sparkling waves in glee:
+A poet could not but be gay,
+In such a jocund company:
+I gazed--and gazed--but little thought
+What wealth the show to me had brought:
+
+For oft, when on my couch I lie
+In vacant or in pensive mood,
+They flash upon that inward eye
+Which is the bliss of solitude;
+And then my heart with pleasure fills,
+And dances with the daffodils.

+And twinkle on the milky way,
+They stretched in never-ending line
+Along the margin of a bay:
+Ten thousand saw I at a glance,
+Tossing their heads in sprightly dance.
+
+The waves beside them danced; but they
+Out-did the sparkling waves in glee:
+A poet could not but be gay,
+In such a jocund company:
+I gazed--and gazed--but little thought
+What wealth the show to me had brought:
+
+For oft, when on my couch I lie
+In vacant or in pensive mood,
+They flash upon that inward eye
+Which is the bliss of solitude;
+And then my heart with pleasure fills,
+And dances with the daffodils.

+# plan type, or perhaps just a regression test whose results aren't fully
+# determinate (eg, due to lack of an ORDER BY keyword).
+#
+# Run this in the src/test/regress directory, after doing the usual setup
+# for a regular regression test, ie, "make clean all" (you should be ready
+# to do "make runtest").
+#
+# The backend option switches that we use here are:
+#	-fs	disable sequential scans
+#	-fi	disable index scans
+#	-fn	disable nestloop joins
+#	-fm	disable merge joins
+#	-fh	disable hash joins
+# Only mergejoin and hashjoin are really guaranteed to turn off; the others
+# just bias the optimizer's cost calculations heavily against that choice.
+# There's no point in trying to turn off both scan types or all three join
+# types simultaneously; ergo, we have 3*7 = 21 interesting combinations.

+-- Scenario:
+--
+--     A building with a modern TP cable installation where any
+--     of the wall connectors can be used to plug in phones,
+--     ethernet interfaces or local office hubs. The backside
+--     of the wall connectors is wired to one of several patch-
+--     fields in the building.
+--
+--     In the patchfields, there are hubs and all the slots
+--     representing the wall connectors. In addition there are
+--     slots that can represent a phone line from the central
+--     phone system.
+--
+--     Triggers ensure consistency of the patching information.
+--
+--     Functions are used to build up powerful views that let
+--     you look behind the wall when looking at a patchfield
+--     or into a room.

+
+SSL regression tests
+====================
+
+This directory contains a test suite for SSL support. It tests both
+client-side functionality, i.e. verifying server certificates, and
+server-side functionality, i.e. certificate authorization.
+
+CAUTION: The test server run by this test is configured to listen for
+TCP connections on localhost. Any user on the same host is able to
+log in to the test server while the tests are running. Do not run this
+suite on a multi-user system where you don't trust all local users!
+
+Running the tests
+=================
+
+NOTE: You must have given the --enable-tap-tests argument to configure.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install".
+In that case, the code in the installation tree is tested.  With
+"make check", a temporary installation tree is built from the current
+sources and then tested.
+
+Either way, this test initializes, starts, and stops a test Postgres
+cluster that is accessible to other local users!
+
+Certificates
+============
+
+The test suite needs a set of public/private key pairs and certificates to
+run:
+
+root_ca
+	root CA, use to sign the server and client CA certificates.
+
+server_ca
+	CA used to sign server certificates.
+
+client_ca
+	CA used to sign client certificates.
+
+server-cn-only
+server-cn-and-alt-names
+server-single-alt-name
+server-multiple-alt-names
+server-no-names
+	server certificates, with small variations in the hostnames present
+        in the certificate. Signed by server_ca.
+
+server-ss
+	same as server-cn-only, but self-signed.
+
+server-password
+	same as server-cn-only, but password-protected.
+
+client
+	a client certificate, for user "ssltestuser". Signed by client_ca.
+
+client-revoked
+	like "client", but marked as revoked in the client CA's CRL.
+
+In addition, there are a few files that combine various certificates together
+in the same file:
+
+both-cas-1
+	Contains root_ca.crt, client_ca.crt and server_ca.crt, in that order.
+
+both-cas-2
+	Contains root_ca.crt, server_ca.crt and client_ca.crt, in that order.
+
+root+server_ca
+	Contains root_crt and server_ca.crt. For use as client's "sslrootcert"
+	option.
+
+root+client_ca
+	Contains root_crt and client_ca.crt. For use as server's "ssl_ca_file".
+
+client+client_ca
+	Contains client.crt and client_ca.crt in that order. For use as client's
+	certificate chain.
+
+There are also CRLs for each of the CAs: root.crl, server.crl and client.crl.
+
+For convenience, all of these keypairs and certificates are included in the
+ssl/ subdirectory. The Makefile also contains a rule, "make sslfiles", to
+recreate them if you need to make changes.
+
+TODO
+====
+
+* Allow the client-side of the tests to be run on different host easily.
+  Currently, you have to manually set up the certificates for the right
+  hostname, and modify the test file to skip setting up the server. And you
+  have to modify the server to accept connections from the client host.
+
+* Test having multiple server certificates, so that the private key chooses
+  the certificate to present to clients. (And the same in the client-side.)

+# - ssl/root+client_ca.crt as the CA root for validating client certs.
+# - reject non-SSL connections

+# The server is configured to only accept connections from localhost. If you

+Regression tests for subscription/logical replication
+=====================================================
+
+This directory contains a test suite for subscription/logical replication.
+
+Running the tests
+=================
+
+NOTE: You must have given the --enable-tap-tests argument to configure.
+
+Run
+    make check
+or
+    make installcheck
+You can use "make installcheck" if you previously did "make install"
+(including installing the hstore extension).  In that case, the code
+in the installation tree is tested.  With "make check", a temporary
+installation tree is built from the current sources and then tested.
+
+Either way, this test initializes, starts, and stops several test Postgres
+clusters.

+# identity index using RelationGetIndexAttrBitmap() would run

+# but there wasn't one set, so it crashes.  There were actually two
