History

Tom Lane 767c598954 Work around implementation restriction in adjust_appendrel_attrs. adjust_appendrel_attrs can't transfer nullingrel labeling to a non-Var translation expression (mainly because it's too late to wrap such an expression in a PlaceHolderVar). I'd supposed in commit `2489d76c4` that that restriction was unreachable because we'd not attempt to push problematic clauses down to an appendrel child relation. I forgot that set_append_rel_size blindly converts all the parent rel's joininfo clauses to child clauses, and that list could well contain clauses from above a nulling outer join. We might eventually have to devise a direct fix for this implementation restriction, but for now it seems enough to filter out troublesome clauses while constructing the child's joininfo list. Such clauses are certainly not useful while constructing paths for the child rel; they'll have to be applied later when we join the completed appendrel to something else. So we don't need them here, and omitting them from the list should save a few cycles while processing the child rel. Per bug #17832 from Marko Tiikkaja.

README

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
