Well, pg_class contains the tables - relname holds the name. I've just tried
deleting a table from it and using pg_dump and it seemed to work.
Having said that, I'd be tempted to pg_dump all the other tables individually
and then give it a go - I'm always a little uneasy about tinkering with the
system tables even when the developers say it should be fine.
