Re: Propose: enum with all registered table names?

A fairly large problem with either regclass or a hypothetical
system-maintained enum is that a table with such a column effectively
has a data dependency on all the tables it mentions.  Which pg_dump
won't know about, so it might try to restore that table before it's
finished creating all the mentioned tables.

I think this will actually work alright in existing pg_dump releases
because it does all the table creation DDL before trying to load any
data.  You might have some problems with future parallel pg_restores
though.

On the whole I'd recommend staying away from the idea.  It doesn't
seem valuable enough to be worth taking risks over.
