Just out of curiosity, why are these needed for TABLE_PRIVILEGES?

One thing to bear in mind is that the existing notion of databases
may need to be rethought when we implement SQL-style schemas (which
I hope will happen for 7.2).  It might be best to refrain from inventing
more functions until we see how the schema work settles out.

I haven't yet heard any serious discussion about how to integrate
the SQL-defined schema concepts with Postgres' traditional concept of
independent databases within an installation.  It's about time to have
that discussion though ...
