Michael Paquier c5b2975ec1 Remove recovery test 011_crash_recovery.pl This test has been added as of `857ee8e` that has introduced the SQL function txid_status(), with the purpose of checking that a transaction ID still in-progress during a crash is correctly marked as aborted after recovery finishes. This test is unstable, and some configuration scenarios may that easier to reproduce (wal_level=minimal, wal_compression=on) because the WAL holding the information about the in-progress transaction ID may not have made it to disk yet, hence a post-crash recovery may cause the same XID to be reused, triggering a test failure. We have discussed a few approaches, like making this function force a WAL flush to make it reliable across crashes, but we don't want to pay a performance penalty in some scenarios, as well. The test could have been tweaked to enforce a checkpoint but that actually breaks the promise of the test to rely on a stable result of txid_status() after a crash. This issue has been reported a few times across the past years, with an original report from Kyotaro Horiguchi. The buildfarm machines tanager, hachi and gokiburi enable wal_compression, and fail on this test periodically.

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
