Somebody from the pgsql-general(at)postgresql(dot)org list, mentioned using
"dblink" to possibly do what I'm looking for.

===========================
Check out "dblink" in the contrib path of the source distribution, I think
it
does what you are looking for.

You didn't mention what your application was but, you might want to
consider
tools like Perl's DBI as well, which (within one script) can connect to
several
DB's.  Of course that method is NOT within the database...

.it would be nice if pl/perl could use modules (can it use modules??).
That
might open up some interesting functionalities  :)

No. You would use middleware for that.
