I'm sorry, I'm confused by your reply. I may have said "table" when I
meant "database". I believe it absolutely *does* make sense to
connect without specifying a database first. What if you hit that
edge case where there are in fact no databases? I suppose you could
always run "createdb" just in case before you do anything else, but
that seems counterintuitive.

What do you mean when you say the "catalogs...are database-
specific" ? If I'm understanding what you're saying, my whole point
is that I don't want to be tied to a database to do any kind of
querying about the PG engine itself. Does that make sense?
