Careful about Debian minor version numbers
Removed obsolete code for installing server_redhat packages with explicit names.

I suspect this resulted from a merge accident. This code was originally removed
in the 2012-08-06 commit for "[COOK-1532] - specify packages with attributes",
but it reappeared in the 2012-11-05 commit for "Support for postgresql 9.0.x on
opensuse 11.4".

Clearly, the old code badly breaks the redhat family for postgresql-9.X, and
since it probably has no effect in opensuse, I just decided to remove it.
Run initdb for any redhat-derived platform version on first install

This should have been done in the 2012-11-02 commit to "[COOK-1844]
Make service name configurable." That change corrected the initdb
call with the version-specific service name, and it also removed
the comment about the code being not valid for 9.x. It should have
removed the "if node[postgresql][version].to_f < 9.0", too.

That is what I have done, to complete that fix.
Optional postgresql::config recipe to install useful administration tools to support postgresql::server
