[postgis-users] Mapguide and PostGis - Using Filters

[Scott, Brian]

Hi Mateusz - 

Thanks for the info.  We are indeed using the OGR provider.  I'm having difficulty finding a compiled version of the native PostGIS FDO provider, which I would be very interested in trying.  Can you point me in the right direction? 

Thank you for your rapid response.

Brian,

What FDO provider do you use to access PostGIS database?
There are two solutions: OGR and native PostGIS provider.
The latter is in pre-1.0 version currently being tested,
so if you're using this native FDO PostGIS provider
I'm strongly interested in solving this issue if it does not work for you.

I'f not played with OGR provider a lot but I confirm that I tested
filters in the native FDO PostGIS provider with success.
Obviously, it's possible there are places which do not work well yet.
