Noah Misch 0f69beddea For inplace update, send nontransactional invalidations. 
The inplace update survives ROLLBACK.  The inval didn't, so another
backend's DDL could then update the row without incorporating the
inplace update.  In the test this fixes, a mix of CREATE INDEX and ALTER
TABLE resulted in a table with an index, yet relhasindex=f.  That is a
source of index corruption.

Back-patch to v14 - v17.  This is a back-patch of commits:

- 243e9b40f1
  (main change, on master, before v18 branched)
- 0bada39c83
  (defect fix, on master, before v18 branched)
- bae8ca82fd
  (cosmetics from post-commit review, on REL_18_STABLE)

It reverses commit c1099dd745, my revert
of the original back-patch of 243e9b4.

This back-patch omits the non-comment heap_decode() changes.  I find
those changes removed harmless code that was last necessary in v13.  See
discussion thread for details.  The back branches aren't the place to
remove such code.

Like the original back-patch, this doesn't change WAL, because these
branches use end-of-recovery SIResetAll().  All branches change the ABI
of extern function PrepareToInvalidateCacheTuple().  No PGXN extension
calls that, and there's no apparent use case in extensions.  Expect
".abi-compliance-history" edits to follow.

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
