Unlikely that any of those config settings would anything to do with it,
but without more info we're kind of flying blind. I'm going to guess
your either not COMMITting your transaction when your done, or your
getting an error your unaware of. Check your database logs (or turn them
on in postgresql.conf if needed) and post back to the list with an error
message and version information.
