I looked around the postgres user account directory and it appears that PostgreSQL is installed there which confuses me because I can’t find any information about that or how to start or access it in that manner. Do you mean is there a data directory under postgres user home directory? Can you run pg_ctl to start the cluster from within such directory? > 5. Looking for advice on how to unravel this situation and get my install up and running. I do have 1 database associated with some Java Web Development in this implementation. Any chance you can understand if data under the postgres user has the size you expect the database to have? I'm not a mac user, but I suspect the upgrade destroyed your installation. Luca
