Improve stability of tests for VACUUM (SKIP_LOCKED)
Concurrent autovacuums running with the main regression test suite
could cause the tests with VACUUM (SKIP_LOCKED) to generate randomly
WARNING messages. For these tests, set client_min_messages to ERROR to
get rid of those random failures, as disabling autovacuum for the
relations operated would not completely close the failure window.
For isolation tests, disable autovacuum for the relations vacuumed with
SKIP_LOCKED. The tests are designed so as LOCK commands are taken
in a first session before running a concurrent VACUUM (SKIP_LOCKED) in a
second to generate WARNING messages, but a concurrent autovacuum could
cause the tests to be slower.
