It seems a pity to throw away perfectly good test cases just because
they increase how long the suite takes to run.

This seems like yet another example of where we could have made good
use of the 'PG_TEST_EXTRA' environment variable. I have been trying to
propose adding "subscription" support for this in another thread [1].
By using this variable to make some tests conditional, we could have
the best of both worlds. e.g.
- retain all tests, but
- by default, only run a subset of those tests (to keep default test
execution time low).

I hope that if the idea to use PG_TEST_EXTRA for "subscription" tests
gets accepted then later we can revisit this, and put all the removed
extra test cases back in again.
