Tom Lane 52898c63e7 Make INSERT-from-multiple-VALUES-rows handle domain target columns. Commit `a3c7a993d` fixed some cases involving target columns that are arrays or composites by applying transformAssignedExpr to the VALUES entries, and then stripping off any assignment ArrayRefs or FieldStores that the transformation added. But I forgot about domains over arrays or composites :-(. Such cases would either fail with surprising complaints about mismatched datatypes, or insert unexpected coercions that could lead to odd results. To fix, extend the stripping logic to get rid of CoerceToDomain if it's atop an ArrayRef or FieldStore. While poking at this, I realized that there's a poorly documented and not-at-all-tested behavior nearby: we coerce each VALUES column to the domain type separately, and rely on the rewriter to merge those operations so that the domain constraints are checked only once. If that merging did not happen, it's entirely possible that we'd get unexpected domain constraint failures due to checking a partially-updated container value. There's no bug there, but while we're here let's improve the commentary about it and add some test cases that explicitly exercise that behavior. Per bug #18393 from Pablo Kharo. Back-patch to all supported branches. Discussion: https://postgr.es/m/18393-65fedb1a0de9260d@postgresql.org		2024-03-14 14:57:16 -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.

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
