Jetspeed2-multiDb - Postgres schema missing?

[Dan Taylor]

Hi,
I've had trouble trying to set up Jetspeed2-multiDb to use my own pre-installed 
Postgres database.
 
I've examined the installer Jar and found database schemas for mysql and other 
databases, but not Postgres. If the installer is indeed missing a Postgres 
schema, has anyone created one for installing Jetspeed2 to use Postgres.
If I've missed something obvious, I'd be glad to be corrected.
Regards
Dan
