The other cases are not quite the same situation.  It would be good to
accept interrupts in all cases, but there's no problem with a session
continuing to be used after a failure in configure_remote_session()
because the connection hasn't been entered in the hash table at that
point yet, and the TRY/CATCH block in connect_pg_server() ensures that
the connection also gets closed.  So we don't need to worry about
those statements leaving behind messed-up sessions; they won't; only
the transaction control commands have that part of the problem.
