Hi there, I guess this is a typical user error. I searched around to find the solution, but in vain. I just upgraded to Lion, and used Kyngchaos libraries for installation of Postgres. Try to get running postgres, and I get this: /usr/local/pgsql-9.1/bin/psql -U postgres psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? In my limited understanding, it seems that Postgres is not running. When I use: ps auxw | grep post out comes only the "grep post", but no postgres process. When I use: sudo launchctl load /Library/LaunchDaemons/org.postgresql.postgres.plist it says: org.postgresql.postgres: Already loaded and displays in the "ps" list then: user 935 0.0 0.1 2493888 7296 ??

I am somewhat lost (and worse is that it worked the other day, before re-installing Lion anew.).
