Yeah, I proposed this a decade ago but never had the wits to write the
code.

It would be very useful for running tests standalone, too -- much as I
dislike 'make installcheck' taking half a minute, I dislike much more
having to take 5 minutes each time to figure out that create_table
depends on box, polygon, create_function, yadda yadda.
