hey,

create the users like posgre and other users through "useradd" command.
Normally these users are created when u install the packages or rpms.

useradd postgre

IIRC, if you did an upgrade instead of a clean install, rpm creates
a .rpmnew (the new file) or .rpmsave (the old file) file for each
critical configuration file that needs to be replaced.

Check and see if you have a /etc/passwd.rpmnew or /etc/passwd.rpmsave
file.  If so you probably also have a matching /etc/shadow.rpmxxx file.
If these files exist then it is likely you will need to manually merge
the changes into the /etc/passwd and /etc/shadow files.
