QTNTernary() contains logic to flatten, eg, '(a & b) & c' into 'a & b & c', which is all well and good, but it tries to do that to NOT nodes as well, so that '!!a' gets changed to '!a'. Explicitly restrict the conversion to be done only on AND and OR nodes, and add a test case illustrating the bug. In passing, provide some comments for the sadly naked functions in tsquery_util.c, and simplify some baroque logic in QTNFree(), which I think may have been leaking some items it intended to free. Noted while investigating a complaint from Andreas Seltenreich. Back-patch to all supported versions.
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
