postgresql version for Kontor 13

I'm having trouble with the pgsql installation. I'm trying to install Kontor 13. Following the HowTo steps, I'm
supposedto find this two files: 
 

• postgresql-6.5.3-3.i386.rpm @ 2318k
• postgresql-server-6.5.3-3.i386.rpm@ 594K
but I've only found:
- postgresql-server-7.3.4-1PGDG.i386.rpm
- postgresql-7.3.4-1PGDG.i386.rpm
I'm supposed to find the ftp://ftp.postgresql.org/pub/RPM directory, but it doesn't exist at all. I've found the
lasttwo files in other directories. 
I'm trying to install those last two in Red Hat 8 (in other computer), but I've got this messages:
error: failed dependencies:
libpq.so.3 is needed by postgresql-7.3.4-1PGDG.i386
postgresql = 7.2.2 is needed by (installed) postgresql-server-7.2.2-1
by the way, I'm new at this, I mean, Linux and Postgresql. If anybody can tell me where i can find the first two
archivesI'd be really thankfull
