That is annoying, I can understand that.

This made sense before we had mappings support because the only user you
could possibly be in PG is the one you authenticated as.

Well, I havn't moved all my systems to GSSAPI yet.. :)

Now that we have support for mappings, I expect it will be more common
for a user to authenticate with princ 'A' and then connect using their
Unix id 'B' to a PG user 'B'. As such, I'm alright with dropping
support for this. Users can always use -U (or equiv) if necessary.
