History

Peter Geoghegan 3499df0dee Support disabling index bypassing by VACUUM. Generalize the INDEX_CLEANUP VACUUM parameter (and the corresponding reloption): make it into a ternary style boolean parameter. It now exposes a third option, "auto". The "auto" option (which is now the default) enables the "bypass index vacuuming" optimization added by commit `1e55e7d1`. "VACUUM (INDEX_CLEANUP TRUE)" is redefined to once again make VACUUM simply do any required index vacuuming, regardless of how few dead tuples are encountered during the first scan of the target heap relation (unless there are exactly zero). This gives users a way of opting out of the "bypass index vacuuming" optimization, if for whatever reason that proves necessary. It is also expected to be used by PostgreSQL developers as a testing option from time to time. "VACUUM (INDEX_CLEANUP FALSE)" does the same thing as it always has: it forcibly disables both index vacuuming and index cleanup. It's not expected to be used much in PostgreSQL 14. The failsafe mechanism added by commit `1e55e7d1` addresses the same problem in a simpler way. INDEX_CLEANUP can now be thought of as a testing and compatibility option.

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
