Actually, that idea might be worth pursuing. Right now pg_regress.c has a
hard-wired notion that it should ALTER DATABASE SET certain parameters on
the regression database. The best you can say for that is it's ugly as
sin. It'd definitely be nicer if we could move that into someplace where
it's more readily adjustable. Having done that, locking down most stuff
by default might become more practical.
However, I'm not sure that just dumping the responsibility into an initial
test script is very workable. We'd need another copy for each contrib
and PL test suite, the isolation tests, yadda yadda. And maintaining
that many copies would be a nightmare. I think we'd need some way to have
pg_regress pick up the desired settings from a central place.
