relevant to the question of whether it makes sense to connect without
being connected to a specific database.  It doesn't, because the
catalogs that you have to inspect to find out anything are
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?
