Right, just wanted to make sure no one had issue with this approach.

I'll look around and see, though my hunch is that, at some point, we
were just pulling all functions and then an optimization was added to
exclude pg_catalog and no one noticed that it broke casts using built-in

Ok, great, I'll get to work on building and testing all supported
versions of pg_dump vs. all server versions that I can reasonably get to
