Custom Dump (just function and trigger)

Dear friend,
Sorry, that was night i couldn't waiting
for you. There's something makes me home
early. So as we discuss about how do i
could do the dump (with pg_dump) but i
just need the script of function, rule,
and create trigger only (without create
table, constraint and create schema).

That's all i need coz i have two IT-Base
on different city and we all need the
newest function or trigger we've modified.

Perhaps you have some idea or tricky-way,
to solve my-prob, that's will make our
job easier. `till now we must editing the
result of pg_dump or sometimes we're open
table pg_proc and put via copy-paste from
field "prosrc".

Thank's so much. and...
GOD Bless You.
