I'd read that message but found "install all dependencies manually" left
me with questions. 

Primarily, What is the best "root" package of a dependency tree to get a
non-db-specific install? spacewalk-base?

Are there aspects (scripts, commands) of system setup using Postgres that
I'd then be missing?

Thanks,
Matt
