let's not even talk about FDO class naming conventions, I'm way too scarred
that experience

OGR is a generic provider, whereas the specific providers should use the
database optimised approach to extracts extents, I'm pretty certain the
PostgreSQL/PostGIS provider is going to be better that the reliable brute

it's easy enough to test this, just create a feature source and see how
long it
take to initialise
