+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

+# This is generally needed to provide a guarantee of a successful INSERT or

+# 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

+# 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
