Michael Paquier 7e61e4cc7c Make two-phase tests of ECPG and main suite more concurrent-proof
The ECPG and main 2PC tests have been using rather-generic names for the
prepared transactions they generate.  This commit switches the 2PC
transactions to use more complex GIDs, reducing the risk of naming
conflicts.

The main 2PC tests also include scans of pg_prepared_xacts that do not
apply filters on the GID of the prepared transactions, making it
possible to fail the test when any 2PC transaction runs concurrently.
The CI has been able to see such failures with an installcheck
running the ECPG and the main regression test suites in parallel.  The
queries on pg_prepared_xacts gain quals to only look after the GIDs
generated locally.

The race is very hard to reproduce, so no backbatch is done for now.

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
