A command-line argument is probably a bad idea (for cases like when you
start psql via a script (or a make file), ...).  An env-var would be good.

Sounds like a good idea.

Such tools often offer things like a `listcompletions' commands which
Emacs can use to implement the completion itself.  Such a thing is used by
GUD for gdb.  Standardizing support for such things directly in comint might
also be a good idea, tho not as good because it only works for those
programs that go to the trouble of providing a `listcompletions' command.
