>> \quit 4
As \q does not currently have an argument, this seems an easy and
reasonnable extension.
However, currently there are 4 existing exit status for psql: 0 (ok), 1
(fatal error), 2 (connection error), 3 (script error...). +128 status are
also already used when killing a psql process.
ISTM that quitting with a status should not interfere with these cases at
least, because a shell could not rely on the exit status to know what went
wrong? Now having \q 1/2/3 forbidden would also be a strange behavior...

With minimal luck the second form would probably work out of box if "\quit
<int>" is implemented because of the way variable substitutions are
performed.
