When copying the definition of an index rebuilt concurrently for the new entry, the index information was taken directly from the old index using the relation cache. In this case, predicates and expressions have some post-processing to prepare things for the planner, which loses some information including the collations added in any of them. This inconsistency can cause issues when attempting for example a table rewrite, and makes the new indexes rebuilt concurrently inconsistent with the old entries. In order to fix the problem, fetch expressions and predicates directly from the catalog of the old entry, and fill in IndexInfo for the new index with that. This makes the process more consistent with DefineIndex(), and the code is refactored with the addition of a routine to create an IndexInfo node.

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
