History

Tom Lane fedc97cdfd Remove ruleutils.c's special case for BIT [VARYING] literals. Up to now, get_const_expr() insisted on prefixing BIT and VARBIT literals with 'B'. That's not really necessary, because we always append explicit-cast syntax to identify the constant's type. Moreover, it's subtly wrong for VARBIT, because the parser will interpret B'...' as '...'::"bit"; see make_const() which explicitly assigns type BITOID for a T_BitString literal. So what had been a simple VARBIT literal is reconstructed as ('...'::"bit")::varbit, which is not the same thing, at least not before constant folding. This results in odd differences after dump/restore, as complained of by the patch submitter, and it could result in actual failures in partitioning or inheritance DDL operations (see commit `542320c2b`, which repaired similar misbehaviors for some other data types). Fixing it is pretty easy: just remove the special case and let the default code path handle these types. We could have kept the special case for BIT only, but there seems little point in that. Like the previous patch, I judge that back-patching this into stable branches wouldn't be a good idea. However, it seems not quite too late for v11, so let's fix it there.

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

examples/
  Demonstration programs for libpq that double as regression tests via
  "make check"

isolation/
  Tests for concurrent behavior at the SQL level

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

thread/
  A thread-safety-testing utility used by configure
