PostgreSQL autostart on Mac OS X

I installed PostgreSQL 9.0 from „One Click Installer” and didn't want it to launch as system starts.

As PostgreSQL has been installed launchctl takes responsibility to take care of always running PostgreSQL daemon. /Library/LaunchDaemons/com.edb.launchd.postgresql-9.0.plist file sets up the daemon's behavior.

There are two options that can prevent the daemon after start up.

<key>Disabled</key>
<false/>

<key>RunAtLoad</key>
<true/>

„Disabled”=True prevents the job from loading at all and there will be not possible start the job even manually.
„RunAtLoad”=Fasle tells the launchctl not to run the job after loading.

Here we are, set „RunAtLoad” to False and the daemon won't be run automatically.

By the way, there are useful commands below to run and stop the daemon though:

sudo launchctl list | grep postgresql

display current daemon's pid or exit code.

sudo launchctl start com.edb.launchd.postgresql-9.0

start the daemon

sudo launchctl stop com.edb.launchd.postgresql-9.0

and stop it
