If we were going to support multiple -f options, it would be sensible
to interpret "-f -" as "read from stdin until EOF".  Then you could
interleave prepared scripts and stdin, which could be pretty handy.
The default behavior would be equivalent to a single instance of "-f -",
and what you are looking for would be "-X -f substitute-psqlrc -f -".

I do think this is potentially cleaner and more general than the
--psqlrc switch.  Maybe that should be reverted and the whole topic
reconsidered during 9.1 devel cycle.
