Jonathan, I do not have this problem solved, but I am further along than I was. Yes, I had postgres 7.0.3 on my machine when I tried to install the rpms. I took your suggestions, but encountered the following errors when trying to remove postgres 7.0.3:
Postgresql is needed by php-pgsql-4.0.4p11-9
Libpg.so is needed by perl-DBD-Pg-0.95-1
Libpg.so is needed by php-pgsql-4.0.4p11-9
Postgresql-devel >= 7.0 is needed by perl-DBD-Pg-0.95-1
I sent you email under a separate email, but have not heard back from you. thanks.
