Just drop the function, drop all triggers that use the function,
re-create the function and recreate all triggers. If the function is
called by other PL functions, you need to drop and re-install those as
well. If you keep them all in a big file, every one preceded by drop,
you can just reload the file (with \i into psql) whenever you have
changed something. No need to dump any data.
