Ensure the pg bin files fallback for geo-postgresql
Ensure the pg bin files fallback for geo-postgresql

Fallback to the geo-postgresql data version before the default

This should fix an issue were geo-postgresql tracking databases on
their own nodes would end up using the default postgres binary even
if their data dir was different.
