No, because there isn't any @ in the incoming connection request in the
normal-user case: just a user name and a database name, which *we* have
to assemble into user@database.

We can't really expect the users to do this for us (give user@database
as their full user name).  There are a number of reasons why I don't
wanna do that, but the real showstopper is that the username field of
the connection request packet is only 32 bytes wide, and we cannot
enlarge it without a protocol breakage.  Fitting "user@database" in 32
bytes would be awfully restrictive about your user and database names.
