Postgresql vs OS compatibility matrix

Hi

We installed our Postgresql package from the RH CDROM v9.
The version is v7.3.2

Is there a compatibility matrix for Postgresql vs OS that I can verify?

I have checked the ftp sites for Postgresql software under the binary/RPMS
folder and discovered that v7.3.2 is not available for redhat 9.0
Only v7.3.3 and above is available for redhat 9.0


Thank you,
REgards.
