Title: postgresql adapter option added

In rare cases we need to specify postgresql adapter name that is `postgresql` by default, but, for example, for postgis-enabled databases (for geo-spatial applications) it should be `postgis`. I've add this option as `WERCKER_POSTGRESQL_ADAPTER` env variable or just `postgresql` if this variable is empty.
