Hm. My experience in the past was that the best way to test an external
AM is to run the core regression tests with a different
default_table_access_method. That does require some work of ensuring the
AM is installed and the relevant extension created, which in turn
requires a different test schedule, or hacking template1. So likely a
different test script anyway?

Possible - still think it'd be best to get the minimal thing in asap,
and then try to extend further afterwards... Perfect being the enemy of
good and all that.
