Yeah, you're probably right. Actually, I couldn't find anything that looks like
"common settings", and so far I've placed it into psql_start_test as a psql
argument. But not sure, maybe there is a better place.

I can't imagine, what kind of test would need to forcibly show the table access
method of all the tables? Even if you need to verify tableam for something,
maybe it's even easier just to select it from pg_am?

Right, fixed.

Well, this grouping looks strange for me. But since I don't have a strong
opinion, I moved the variable.

Yep.
