HINT: No function matches the given name and argument types. You may

I am looking for a an alternative to manually issuing alter sequence

Does pg_get_serial_sequence() exist as plpgsql code? Where may I find it? I would like to retrofit it into a 7.4.8 PG database.
Thanks
This allows automated scripts to reliably find the SERIAL sequence name.
If you use a 7.x copy of pg_dump it might work, though there could be
catalog changes that make that a problem.
