I (again) re-installed Lion from scratch, and finally got everything working. The Postgres was running, I uploaded a couple of dumped SQL files. And then re-started the machine for another reason. And suddenly it says again the it can't connect to the server. I tried /usr/local/pgsql-9.1/bin/initdb -U postgres -D /usr/local/pgsql-9.1/data --encoding=UTF8 --locale=en_US and /usr/local/pgsql-9.1/bin/pg_ctl -D /usr/local/pgsql-9.1/data/ -l logfile start and sudo launchctl load /Library/LaunchDaemons/org.postgresql.postgres.plist … but nothing happens. I don't have the feeling that it's a problem with the "postgres" and "_postgres" users (as it has worked before already). Can anyone give me a hint how I can figure out where the problem lies and what I can do about it? Why did it work before I restarted the computer and why does it not work anymore? Thanks a lot for any hints! -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
