Good idea, but that is only going to work on Unix, and in fact only
using certain shells. I don't think we want to go there, do we? I
could expand that out to a normal shell _if_ statement, but again, only
works on Unix.
What we _could_ do is to add a comment line at the top that defines a
string that can be supplied, and default it to the port number; that
would work on Unix and Windows, e.g.
# uncomment and adjust if you want a special port number
# PGPORT_STR="-p 5435"
# export PGPORT
For Windows it would be "REM". Is everyone happy with that?
