The EvalPlanQual recheck for TID Range Scan wasn't rechecking the TID qual still passed after following update chains. This could result in tuples being updated or deleted by plans using TID Range Scans where the ctid of the new (updated) tuple no longer matches the clause of the scan. This isn't desired behavior, and isn't consistent with what would happen if the chosen plan had used an Index or Seq Scan, and that could lead to hard to predict behavior for scans that contain TID quals and other quals as the planner has freedom to choose TID Range or some other non-TID scan method for such queries, and the chosen plan could change at any moment. Here we fix this by properly implementing the recheck function for TID Range Scans.

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
