Well, done.  One thing that I find a bit surprising in all that is the 
lack of consistency in the handling of the return code of psql when
the last switch fails when not using ON_ERROR_STOP.  For example, psql
fails if the last switch is a slash command from -c, but succeeds if
the last switch is a slash command in a file from -f that exists.
This comes down to the way failures are passed down from MainLoop() so
I am not sure if this is worth worrying about and nobody has
complained about that AFAIK, but I have added some extra tests to at
least document everything I could think about to track changes, in
case somebody plays with this code in the future.
