I'd use GFS to make sure that data is not corrupted. You can "live" with
ext3 -- but in case of a problem, if two postmaster directly accesses the
same node, data problem may occur.

is the link to the presentation that I made at 10th PostgreSQL Anniversary
Summit last year; which will give you a basic idea about these issues.

AFAIR you will need to change condstart routines to start routines for
RHCS to start PostgreSQL correctly. So PostgreSQL's init script should be
fine.
