Álvaro Herrera ea06f97eeb Stop creating constraints during DETACH CONCURRENTLY Commit `71f4c8c6f7` (which implemented DETACH CONCURRENTLY) added code to create a separate table constraint when a table is detached concurrently, identical to the partition constraint, on the theory that such a constraint was needed in case the optimizer had constructed any query plans that depended on the constraint being there. However, that theory was apparently bogus because any such plans would be invalidated. For hash partitioning, those constraints are problematic, because their expressions reference the OID of the parent partitioned table, to which the detached table is no longer related; this causes all sorts of problems (such as inability of restoring a pg_dump of that table, and the table no longer working properly if the partitioned table is later dropped). We'd like to get rid of all those constraints. In fact, for branch master, do that -- no longer create any substitute constraints. However, out of fear that some users might somehow depend on these constraints for other partitioning strategies, for stable branches (back to 14, which added DETACH CONCURRENTLY), only do it for hash partitioning. (If you repeatedly DETACH CONCURRENTLY and then ATTACH a partition, then with this constraint addition you don't need to scan the table in the ATTACH step, which presumably is good. But if users really valued this feature, they would have requested that it worked for non-concurrent DETACH also.)

README

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
