Replace CLOBBER_CACHE_ALWAYS with run-time GUC
Forced cache invalidation (CLOBBER_CACHE_ALWAYS) has been impractical
to use for testing in PostgreSQL because it's so slow and because it's
toggled on/off only at build time. It is helpful when hunting bugs in
any code that uses the sycache/relcache
Add a test module for the regular expression package.
This module provides a function test_regex() that is functionally
rather like regexp_matches(), but with additional debugging-oriented
options and additional output. The debug options are somewhat obscure;
they are chosen to match the API of t
Report progress of COPY commands
This commit introduces a view pg_stat_progress_copy, reporting progress
of COPY commands. This allows rough estimates how far a running COPY
progressed, with the caveat that the total number of bytes may not be
available in some cases (e.g. when the input comes fr
Add idle_session_timeout.
This GUC variable works much like idle_in_transaction_session_timeout,
in that it kills sessions that have waited too long for a new client
query. But it applies when we're not in a transaction, rather than
when we are.

Improve timeout.c's handling of repeated timeout set/cancel.
A very common usage pattern is that we set a timeout that we don't
expect to reach, cancel it after a little bit, and later repeat.
With the original implementation of timeout.c, this results in one
setitimer() call per timeout set or ca
Fix allocation logic of cryptohash context data with OpenSSL
The allocation of the cryptohash context data when building with OpenSSL
was happening in the memory context of the caller of
pg_cryptohash_create(), which could lead to issues with resowner cleanup
if cascading resources are cleaned up
Improve commentary in timeout.c.
On re-reading I realized that I'd missed one race condition in the new
timeout code. It's safe, but add a comment explaining it.

Fix bogus link in test comments.
I apparently copied-and-pasted the wrong link in commit ca8217c10.
