From http://www.postgresql.org/docs/8.1/interactive/release-8-0.html:

# Add pg_get_serial_sequence() to return a SERIAL column's sequence name
(Christopher)

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.
