In 8.3, running \c from a file prints something like

You are now connected to database "postgres".

In 8.4 it prints

psql (8.4.1)
You are now connected to database "postgres".

Is it intentional/sensible to repeat the startup banner every time the
connection changes, or was this unintentionally introduced while the
startup banner was reshuffled in 8.4?
