This removes md5() function calls from these test suites:
- bloom
- test_decoding
- isolation
- recovery
- subscription
This covers all remaining test suites where md5() calls were just used
to generate some random data and can be replaced by appropriately
adapted sha256() calls. This will eventually allow these tests to
pass in OpenSSL FIPS mode (which does not allow MD5 use). See also
208bf364a9. Unlike for the main regression tests, I didn't write a
fipshash() wrapper here, because that would have been too repetitive
and wouldn't really save much here. In some cases it was easier to
remove one layer of indirection by changing column types from text to
bytea.

In-core relation options can use a custom lock mode since 47167b7, that
has lowered the lock available for some autovacuum parameters. However
it forgot to consider custom relation options. This causes failures
with ALTER TABLE SET when changing a custom relation option, as its lock
is not defined. The existing APIs to define a custom reloption does not
allow to define a custom lock mode, so enforce its initialization to
AccessExclusiveMode which should be safe enough in all cases. An
upcoming patch will extend the existing APIs to allow a custom lock mode
to be defined.
The problem can be reproduced with bloom indexes, so add a test there.

This is preparation for a future patch to extensively change how

blbuildempty did not do even approximately the right thing: it tried
to add a metapage to the relation's regular data fork, which already
has one at that point. It should look like the ambuildempty methods
for all the standard index types, ie, initialize a metapage image in
some transient storage and then write it directly to the init fork.
To support that, refactor BloomInitMetapage into two functions.
In passing, fix BloomInitMetapage so it doesn't leave the rd_options
field of the index's relcache entry pointing at transient storage.
I'm not sure this had any visible consequence, since nothing much
else is likely to look at a bloom index's rd_options, but it's
certainly poor practice.
Per bug #14155 from Zhou Digoal.

Originally, this test created a 100000-row test table, which made it
run rather slowly compared to other contrib tests. Investigation with
gcov showed that we got no further improvement in code coverage after
the first 700 or so rows, making the large table 99% a waste of time.
Cut it back to 2000 rows to fix the runtime problem and still leave
some headroom for testing behaviors that may appear later.
A closer look at the gcov results showed that the main coverage
omissions in contrib/bloom occurred because the test never filled more
than one entry in the notFullPage array; which is unsurprising because
it exercised index cleanup only in the scenario of complete table
deletion, allowing every page in the index to become deleted rather
than not-full. Add testing that allows the not-full path to be
exercised as well.
Also, test the amvalidate function, because blvalidate.c had zero
coverage without that, and besides it's a good idea to check for
mistakes in the bloom opclass definitions.

Module provides new access method. It is actually a simple Bloom filter
implemented as pgsql's index. It could give some benefits on search
with large number of columns.
Module is a single way to test generic WAL interface committed earlier.
