ExecFindInitialMatchingSubPlans has to update the PartitionPruneState's subplan mapping data to account for the removal of subplans it prunes. However, that's only necessary if run-time pruning will also occur, so we can skip it when that won't happen, which should result in not needing to do the remapping in many cases. (We now need it only when some partitions are potentially startup-time prunable and others are potentially run-time prunable, which seems like an unusual case.) Also make some marginal performance improvements in the remapping itself. These will mainly win if most partitions got pruned by the startup-time pruning, which is perhaps a debatable assumption in this context. Also fix some bogus comments, and rearrange code to marginally reduce space consumption in the executor's query-lifespan context.

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
