Is it possible to install and then subsequently run the postgres engine on Linux without creating the postgres user and group? We have some folks implementing LDAP that are resistant to creating a postgres account and group and would rather create machine specific accounts (like one does for Windows with SQL Server).
I always thought that if the postgres user and group were not there upon install (which is done as root), that the installation process would create them for you, am I missing something?
Thanks for any input that will provide me with ample ammunition to thwart this silly idea.

Is there any problem with configuring postgres user and group in /etc/passwd
and /etc/group respectively? You can configure PAM to accept user
authentication from multiple sources. See e. g. http://ldots.org/ldap/

The server source code has no particular allegiance to any OS username.
You can run it under whatever account you want.

Particular packagings of Postgres might act like that --- for instance,
the Fedora/Red Hat RPMs would try to create such a user&group. But you
did not say whose packaging you were thinking of using. In any case
you could run the executables under some other user ID if you then
adjusted file ownerships and startup scripts appropriately.

Understood, but I thought that the install routine (in this case compiled from source on RHEL 6) will create the local user and group named postgres and chown the config and data dirs to that ....

The unmodified Postgres sources will certainly do no such thing.

You are correct, it is because I ran initdb as user postgres .... I am following you now .. .thanks for the clarification.
