[Vittorio]

I Just did as suggested but cannot change the result:

MacBookVictor:PostgreSQL victor$ sudo launchctl load -w /Library/ 
LaunchDaemons/org.macports.postgresql83-server.plist
org.macports.postgresql83-server: Already loaded
MacBookVictor:PostgreSQL victor$ sudo launchctl unload /Library/ 
LaunchDaemons/org.macports.postgresql83-server.plist
MacBookVictor:PostgreSQL victor$ sudo launchctl load -w /Library/ 
LaunchDaemons/org.macports.postgresql83-server.plist
MacBookVictor:PostgreSQL victor$ ps ax |grep postgres
  1379   ??  Ss     0:00.01 /opt/local/bin/daemondo -- 
label=postgresql83-server --start-cmd /opt/local/etc/LaunchDaemons/ 
org.macports.postgresql83-server/postgresql83-server.wrapper start ; -- 
stop-cmd /opt/local/etc/LaunchDaemons/org.macports.postgresql83-server/ 
postgresql83-server.wrapper stop ; --restart-cmd /opt/local/etc/ 
LaunchDaemons/org.macports.postgresql83-server/postgresql83- 
server.wrapper restart ; --pid=none
  1384 s000  R+     0:00.00 grep postgres
