I have installed PostgreSQL 7.2 but have problems getting the program to run
properly.

When I try start the postmater with pg_ctl I get the following error message

FATAL 1: The data directory was initialized by PostgreSQL 7.2, which is not
compatible with this version 7.1.3

I gather I must still have a version 7.1.3 on the system (does this come
with Redhat?). Is there a way to remove the old version or upgrade
everything to 7.2?

regards,
KSG
