There are, although we don't spell the commands like that. This is not
relevant to the question of whether it makes sense to connect without

database-specific.

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?
Best,
Michael
