just a guess on my part, but i think what you're going to want to do is
set the PG_DATA environment variable to /usr/local/pgsql/data_5433 in
your script before you start the second instance. they screwed around
with the ability to specify absolute paths to the data directory in
6.4.x and didn't document it, so i'm not sure what the truth is about
it. i'm not sure if that's what is causing the problem in _this case_,
but it has happened with other cases. (it makes good sense to require
you to use environment variables in all cases, as far as i'm
concerned.) i submitted some doc patches, but apparently they haven't
shown up yet.
again, this is just a guess, but an educated one.
