I have just uploaded PostgreSQL 8.2.3 RHEL5 RPMs to main FTP site. The
set includes a compat-4 RPM, so that you will not get dependency
errors. Please follow the regular major upgrade procedure while you are
upgrading from 8.1 set that is shipped with RHEL5.
More news... I pushed my first package (postgresql-dbi-link) to EPEL.
EPEL is Enterprise Linux Extras. With EPEL, RHEL 4 and 5 users can
install more packages that are community-supported. I also submitted
for inclusion of postgis, pgFouine, phpPgAdmin, python-psycopg2 in EPEL.
I hope to add more packages that will help RHEL/Fedora+PostgreSQL users.
