An extra option is to have some tests in core, then control their
execution with a new value in PG_TEST_EXTRA so as one has an easy way
to run the tests that a buildfarm machine would run. We have already
solved any problems related to full pg_regress runs in TAP tests, as
proved by 002_pg_upgrade.pl and 027_stream_regress.pl, but I doubt
that everybody would accept the workload of an extra full run of the
main regression test suite by default for the sake of what's being
developed on this thread.
