[fw-db] Default schema for Postgresql

Hi,

I'm writing some re-usable modules, which use a postgresql database (through pdo).
Is it possible to set the schema in some parameter, so I don't have to change all the DbTable classes when I transport my code?

I tried it in the ini file like:
resources.db.adapter = PDO_PGSQL
resources.db.params.host = localhost
resources.db.params.username = user
resources.db.params.password = pass
resources.db.params.dbname = defaultdb
resources.db.params.schema = myschema

But that doesn't seem to work.
Should this be possible or are there any other possiblities?

Thanks,
Mark
