Well, there'd be a certain amount of circularity in consulting a table
to find out where you can find tables, no? ;-) But you're right, the
environment-variable mechanism is pretty grotty. There's been a great
deal of discussion already in pg-hackers about how to clean up this
and related issues; suggest you consult the archives if you want to get
involved with fixing it.
