How to list only my functions and their content?

I am in psql. I tried "\dd" but this lists pg_catalog and stuff like
that. Long list that I don't need.

I scoured through this page --
http://www.postgresql.org/docs/8.3/static/app-psql.html -- and still
did not find how to list only my own functions? A regular "\d" shows
only tables and views it seems.

All I need is to list my own created functions and their code.

Thanks for any pointers!
