The IANA time zone folk have deprecated use of a "posixrules" file in the tz database. While for now it's our choice whether to keep supplying one in our own builds, installations built with --with-system-tzdata will soon be needing to cope with that file not being present, at least on some platforms. This causes a problem for the horology test, which expected the nonstandard POSIX zone spec "CST7CDT" to apply pre-2007 US daylight savings rules. That does happen if the posixrules file supplies such information, but otherwise the test produces undesired results. To fix, add an explicit transition date rule that matches 2005 practice. (We could alternatively have switched the test to use some real time zone, but it seems useful to have coverage of this type of zone spec.) While at it, update a documentation example that also relied on "CST7CDT"; use a real-world zone name instead. Also, document why the zone names EST5EDT, CST6CDT, MST7MDT, PST8PDT aren't subject to similar failures when "posixrules" is missing. Back-patch to all supported branches, since the hazard is the same for all. Discussion: https://postgr.es/m/1665379.1592581287@sss.pgh.pa.us |

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 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 subscription/ Tests for logical replication thread/ A thread-safety-testing utility used by configure
