statext_is_compatible_clause_internal() checked that the arguments of a ScalarArrayOpExpr are one Var and one Const, but it would allow cases where the Const was on the left. Subsequent uses of the clause are not expecting that and would suffer assertion failures or core dumps. mcv.c also had not bothered to cope with the case of a NULL array constant, which seems really unacceptably sloppy of somebody. (Although our tools failed us there too, since AFAIK neither Coverity nor any compiler warned of the obvious use-of-uninitialized-variable condition.) It seems best to handle that by having statext_is_compatible_clause_internal() reject it. Noted while fixing bug #17570. Back-patch to v13 where the extended stats code grew some awareness of ScalarArrayOpExpr. |

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
