Title: ActiveRecord::ConnectionHandling.postgresql_connection : White list params instead of black listing.

This patch allow only valid params to be send to PGconn to avoid exceptions in case other params are typed in database.yml (Sometime required by customs adapter based on Postgresql-adapter. e.q postgis-adapter)
