Here it is but the result is unchanged:


MacBookVictor:~ victor$ sudo mkdir -p /opt/local/var/db/postgresql83/ 
defaultdb
Password:
MacBookVictor:~ victor$ sudo chown postgres:postgres /opt/local/var/db/ 
postgresql83/defaultdb
MacBookVictor:~ victor$ sudo su postgres -c '/opt/local/lib/ 
postgresql83/bin/initdb -D /opt/local/var/db/postgresql83/defaultdb'
MacBookVictor:~ victor$ sudo launchctl load -w /Library/LaunchDaemons/ 
org.macports.postgresql83-server.plist
org.macports.postgresql83-server: Already loaded
MacBookVictor:~ victor$ ps a|grep postgr
