postgres_real process?

I have set up a brand new Mac OS X Lion Server and installed the postgresql-9.1.4-1-osx.dmg from EnterpriseDB as on many other previous installations.
But now I have two different processes/services and users of PostgreSQL running. A “postgres” process for the “postgres” user and a “postgres_real” process for the “_postgres” User.
Where does the “postgres_real” and user “_postgres” comes from and why do I have this two different postgresql instances?

Hi Thomas,

You say you run Lion Server. This version comes with PostgreSQL bundled (they dropped MySQL in favor of Pg).
So the postgres_real is the one that came with the OS. The other is the EDB installed version.

Hope this helps.

Hi Robert,

is it a problem running both at the same time and do I and/or the OS need the postgres_real?

I don’t like it to have two different PostgreSQL server running.

Hi Thomas,

It’s not a problem to run 2 instances next to each other. Each instance will use their own portnumber.
I believe postgres_real is used for the wiki and such. I did some googling and found the following info on how to connect to this instance.

Hope this helps.

Hi Robert,

thank you!

For me it’s more handy and easier to administrate the EnterpriseDB installation of PSQL because of updating to newer versions etc.
