Here we adjust relation_has_unique_index_for() so that it no longer makes use of partial unique indexes as uniqueness proofs. It is incorrect to use these as the predicates used by check_index_predicates() to set predOK makes use of not only baserestrictinfo quals as proofs, but also qual from join conditions. For relation_has_unique_index_for()'s case, we need to know the relation is unique for a given set of columns before any joins are evaluated, so if predOK was only set to true due to some join qual, then it's unsafe to use such indexes in relation_has_unique_index_for(). The final plan may not even make use of that index, which could result in reading tuples that are not as unique as the planner previously expected them to be.

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
