Missing settings for Postgres install using Macports
I am currently trying to install Postgres on my local Snow Leopard OS using macports.

After installing macports, I run:<br/>
`sudo port install postgresql83 postgresql83-server`

`sudo mkdir -p /opt/local/var/db/postgresql83/defaultdb`

When I run the following line:<br/>
`sudo chown postgres:postgres /opt/local/var/db/postgresql83/defaultdb`

I get the following error:<br/>
`chown: postgres: Invalid argument`

What am I missing?  A setting?
