That's correct, Lucas.  It seems functions are more than just stored
procedures.  Functions are also part of new data types as well (though
are not required to be).
http://postgresql.readysetnet.com/users-lounge/docs/7.0/programmer/xfunc.htm
has the description of them, which I share for any fledgeling PGSQL
programmers out there like myself.  (Especially those of us trying to
get away from MSSQL.)
