I would say the easiest is to use pg_dump and then filter the output.
It's simple enough for sed I think:

pg_dump database | sed -ne '/^CREATE FUNCTION tag/,/^--/p'

works well here... Replace tag with a pattern matching your functions.
If you're using pl/pgsql you may need to do something more clever with
the end marker...

Have a nice day,
