Well, as was pointed out, that's a lot of data to send back if your
primary key is a huge text column, and you've still got a problem if
you have a multi-column primary key.

Since this sort of functionality is not all that frequently needed, I'd
still say it would probably be cleaner to make a new query that selects
the most recently inserted primary key. That means that a) you don't
have to send back a potentially large amount of data unless the user
asks for it, and b) multi-column primary keys work just fine.
