Installation on Ubuntu 13.04 - Mailing list pgsql-pkg-debian

Just wondering if it is possible to install 9.2 on Ubuntu 13.04? I have seen a tutorial or two which basically just says to install the Precise/12.04 packages. When I try to do that I get the following

cat /etc/apt/sources.list.d/pgdg.list
deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main

sudo apt-get install postgresql
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help resolve the situation:

The following packages have unmet dependencies:
 postgresql : Depends: postgresql-9.2 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

So I tried specifying 9.2 directly
sudo apt-get install postgresql-9.2
The following packages have unmet dependencies:
 postgresql-9.2 : Depends: postgresql-common (>= 135~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

And then to specify postgresql-common
sudo apt-get install postgresql-9.2 postgresql-common
The following packages have unmet dependencies:
 postgresql-common : Breaks: logrotate (>= 3.8) but 3.8.3-3ubuntu2 is to be installed
E: Unable to correct problems, you have held broken packages.

I'm at a loss after that
