Hmmm. What did you do to "delete that table" exactly? The crash
suggests that there is a row in pg_rewrite that links to a nonexistent
row in pg_class. It'd be better if pg_dump emitted a more useful
failure message, of course, but the real question is how did your
system catalogs get into such a state ...
