logical decoding: Correctly free speculative insertion
The error path in ReorderBufferProcessTXN was not freeing
(reorderbuffer.c's representation of) a speculative insertion record
correctly.  In assert-enabled builds, this leads to an assertion
failure.  In production builds, I see no effect; there may be a small
transient leak, but in an improbable code path such as this, such a leak
is not of any significance.  For users running with assertions enabled,
the crash is annoying.

Fix by having ReorderBufferProcessTXN() free the speculative insert
ahead of freeing the rest of the transaction, and no longer try to
handle that insert as a separate argument to ReorderBufferResetTXN().

This code came in with commit 7259736a6e (14-era).  Backpatch all the
way back.

In branches 14-16, also backpatch the assertion that originally fails in
the problem scenario, which was added by dbed2e3662 (originally
backpatched to 17), that at the end of ReorderBufferReturnTXN() the
in-memory size of the transaction is zero.

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

ldap/
  Tests for LDAP-based authentication

locale/
  Sanity checks for locale data, encodings, etc

mb/
  Tests for multibyte encoding (UTF-8) support

modules/
  Extensions used only or mainly for test purposes, generally not suitable
  for installing in production databases

perl/
  Infrastructure for Perl-based TAP tests

recovery/
  Test suite for recovery and replication

regress/
  PostgreSQL's main regression test suite, pg_regress

ssl/
  Tests to exercise and verify SSL certificate handling

subscription/
  Tests for logical replication
