Hi,
Postgress has an pg_dump utility wich can be used to dump an entire database (both db structure and content), as a file containing sql commands.
If the ACS/pg team already has an initialised postgress database, with all structure and config data initialised, is simple for them to run pg_dump, then include the dumped file in the ACS/pg distribution.
Then to install it we'll need only to run this sql script against our postgres server in order to initialise the ACS/pg database.

Cezar
