History

Tom Lane ac4a9d92fc Fix incorrect handling of polymorphic aggregates used as window functions. The transfunction was told that its first argument and result were of the window function output type, not the aggregate state type. This'd only matter if the transfunction consults get_fn_expr_argtype, which typically only polymorphic functions would do. Although we have several regression tests around polymorphic aggs, none of them detected this mistake --- in fact, they still didn't fail when I injected the same mistake into nodeAgg.c. So add some more tests covering both plain agg and window-function-agg cases. Per report from Sebastian Luque. Back-patch to 9.6 where the error was introduced (by sloppy refactoring in commit `804163bc2`, looks like). Report: <87int2qkat.fsf@gmail.com>		2016-10-09 12:49:37 -04:00

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.

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

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