[ELGIS] PgRpms PostgreSQL. Why not?

[Carlo A. Bertelli (Charta s.r.l.)]

Hello,
sorry if this is a FAQ, but I didn't find any precise information
about the issues with pgrpms provided PostreSQL packages.
ELGIS is great in providing the most recent version of GIS stuff, but
stickes to EPEL provided version of Pg, which is a fairly old 8.4
version.
What are the specific issues with these packages? Is it feasible to
reconcile the two efforts. It would be much better to have a
continuously updated version of PostgreSQL. So why not?
