Restore support for PgSQL 9.4 and below

The addition of support for PostgreSQL 9.6 and above neglected to change the `Postgres94` class to inherit from `Postgres95` instead of the latest `Postgres` class. This change restores the chain of inheritance, so that `Postgres94` and classes below see overridden methods from `Postgres95` and above.
