Michael Paquier 41a033b505 Preserve index data in pg_statistic across REINDEX CONCURRENTLY Statistics associated to an index got lost after running REINDEX CONCURRENTLY, while the non-concurrent case preserves these correctly. The concurrent and non-concurrent operations need to be consistent for the end-user, and missing statistics would force to wait for a new analyze to happen, which could take some time depending on the activity of the existing autovacuum workers. This issue is fixed by copying any existing entries in pg_statistic associated to the old index to the new one. Note that this copy is already done with the data of the index in the stats collector.

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
