Re: [SQL] how to determine table?

Good question. This is something I desperately want also. I proposed
that there be an imaginary field on all tables called "classoid" for the
oid of the class it belongs to (allowing a join with pg_class) or
perhaps a "relname" imaginary field giving the name of the relation.
Unfortunately it doesn't exist now, and having a real field with the
table name is the best that can be done.
