I didn't attach it since it's the same as the link I referenced in my

It's a scrip to backup and interact with the database so I think it
does. It may not be specifically what this mailing list was intended
for but it's the best suited that I could find not to mention the
script is posted on the main PostgreSQL wiki site so it appears to be
legit and supported...

Thanks for any info!
