Connect to each other DB (as superuser) and issue the CREATE FUNCTION
commands in that DB.

If you have created the functions in template1, subsequently-created DBs
will inherit the definitions automatically, since CREATE DATABASE clones
the state of template1. But for a pre-existing DB, you gotta make the
pg_proc rows over again.
