Tom Lane ce95c54376 Fix pg_statio_all_tables view for multiple TOAST indexes.
A TOAST table can normally have only one index, but there are corner
cases where it has more; for example, transiently during REINDEX
CONCURRENTLY.  In such a case, the pg_statio_all_tables view produced
multiple rows for the owning table, one per TOAST index.  Refactor the
view to avoid that, instead summing the stats across all the indexes,
as we do for regular table indexes.

While this has been wrong for a long time, back-patching seems unwise
due to the difficulty of putting a system view change into back
branches.

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
