i have just switched to posgresql and installed for use with ruby. i need to move my app and database to a new server. since i can shut down the server i think it will be easier for me to do a file system level back up. when i try to shut the server down i get this message sudo -u postgres pg_ctl -D /opt/local/var/db/postgresql82/defaultdb stop pg_ctl: PID file "/opt/local/var/db/postgresql82/defaultdb/ postmaster.pid" does not exist Is server running? it is running. this is my first time attempting this. can someone suggest an easy tutorial on this. also... i have set up the new server with the same permissions so i should be able to move the db to the new location. total newbie
