Sorry if my words were hard to catch here. What I mean here is to add in
each command's test file the set of commands which check the
compatibility. There is no need to test all the options in my opinion,
as just testing one option is enoughto show the purpose. So for example
to cover the grounds of DefineAggregate(), you could add a set of
commands in create_aggregate.sql. For DefineCollation(), those can go in
