I am having installation problems with postrgesql on my mac. I'v tried MacPorts, your site and PostgreSQLforMac. I've tried 8.3.7 and the most current version. After each install I'm unable to locate any actual access to the DB. When installing from the disk image I'm told that the data-base cluster is not found or was improperly installed.
I'm attempting to set up GNUmed, postgresql and the most appropriate version of python.
The mac i'm using is a MacBookPro with 2gig of memory running Leopard.
