There are a couple of options you can take to accomplish this.

1) Remove the role by running ¨roledel postgres¨ . This will remove postgres from /etc/passwd and /etc/user_attr, and you can use useradd to add postgres as a user.

2) Modify ¨postgres¨ from being a role to user. Below are the steps I use:

   a) run ¨passwd -d postgres¨
b) edit /etc/user_attr and change type for ¨postgres¨ from ¨role¨ to ¨user¨
   c) create a home dir for postgres if needed
   d) use the usermod command to change the home dir and shell

I guess what you mean is to remove the "role" postgres so that you can redefine it as a normal user and not remove the binaries that are installed with Postgres as they can be overridden by having right PATH variables

Its easy... Modify /etc/user_attr and remove type=role from the postgres line and modify /etc/passwd to set a home path and change default shell to /bin/sh or /bin/bash and set password for it.. and now you have a normal user..
Is this what you are trying to do?

Hello all,
I have a software solution with a postgres database. The user postgres is abolutly needed for my software. With Solaris 10, Postgres is automatically installed and uses the user postgres. How can I easily remove the current postgres install from this Solaris 10? Is there a process which is provided from Solaris to remove it? Whats the best way to do it? Thank you for your help. Cheers Thomas **
