Tom Lane 182db07040 Fix test about ignoring extension dependencies during extension scripts. Commit `08dd23cec` introduced an exception to the rule that extension member objects can only be dropped as part of dropping the whole extension, intending to allow such drops while running the extension's own creation or update scripts. However, the exception was only applied at the outermost recursion level, because it was modeled on a pre-existing check to ignore dependencies on objects listed in pendingObjects. Bug #14434 from Philippe Beaudoin shows that this is inadequate: in some cases we can reach an extension member object by recursion from another one. (The bug concerns the serial-sequence case; I'm not sure if there are other cases, but there might well be.) To fix, revert 08dd23cec's changes to findDependentObjects() and instead apply the creating_extension exception regardless of stack level. Having seen this example, I'm a bit suspicious that the pendingObjects logic is also wrong and such cases should likewise be allowed at any recursion level. However, changing that would interact in subtle ways with the recursion logic (at least it would need to be moved to after the recursing-from check). Given that the code's been like that a long time, I'll refrain from touching it without a clear example showing it's wrong. Back-patch to all active branches. In HEAD and 9.6, where suitable test infrastructure exists, add a regression test case based on the bug report.

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
