HA for PostgreSQL (Auth-Server)

Hello *,

in my enterprise I have an Intranet-Server with NFSv4, Courier, Apache
and PostgreSQL and if this Server goes down, nothing will work anymore.

OK, I replicate the WHOLE server all 6 hours, but my PostgreSQL give me
a bunch of headache, becasue I use "pam-pgsql" for authentication.

What is the best practize to build the PgSQL in HA using a second/third
external server to keep authentication alive?

I am onging to put, the PostgregSQL on three or more Marvel MV78200 with
attached 4-port SAS controller (using three 74GByte SAS Drives in Raid-1
plus Hotfix) since the Intranet Database itself is only arround 13 GByte

Thanks, Greetings and nice Day/Evening
