Refactors OGR Postgres wrapper to allow for renaming tables on import
WDPA tables imported separately with standardised names

The tables can now be reused later in the downloads, without having to
denormalise the Rails DB back to match the WDPA data standard.

Better, yea?

the rails normalised format.
