I use it all the time for application development; my rebuild script
will forcibly kick everyone out to re-create the database. I put that in
because I invariably end up with a random psql sitting somewhere that I
don't want to track down.

What currently stinks though is if the connection is dead and the next
command I run is a \i, psql just dies instead of re-connecting. It'd be
nice if before reading the script it checked connection status and
attempted a reconnect.

+1, I don't think it needs to be the default.
