History

David Rowley da5800d5fa Don't presort ORDER BY/DISTINCT Aggrefs with volatile functions In `1349d2790`, we gave the planner the ability to provide ORDER BY/DISTINCT Aggrefs with presorted input so that nodeAgg would not have to perform sorts during execution. That commit failed to properly consider the implications of if the Aggref had a volatile function in its ORDER BY/DISTINCT clause. As it happened, this resulted in an ERROR about the volatile function being missing from the targetlist. Here, instead of adding the volatile function to the targetlist, we just never consider an Aggref with a volatile function in its ORDER BY/DISTINCT clause when choosing which Aggrefs we should sort by. We do this as if we were to choose a plan which provided these aggregates with presorted input, then if there were many such aggregates which could all share the same sort order, then it may be surprising if they all shared the same sort sometimes and didn't at other times when some other set of aggregates were given presorted results. We can avoid this inconsistency by just never providing these volatile function aggregates with presorted input.

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
