functions:
\df [optional function name glob]

operators (there are some weird ones):
\do [opt glob]

you may want to use \o filename to redirect output to a file, then you
can use "grep" and such tools to find functs, etc. based on param types
and description text.

(there are, of course, equivalent SQL statements, that do the same thing
as the above psql convienience functions, using the appropriate system
tables (pg_*), which would allow one to avoid files and grep. But for
learning, there's a catch-22, and I already knew how to use grep ;-)
