Another interesting message about using PostGIS as backend to commercial GIS-clients like ESRIs ArcGIS has been submitted to the PostGIS-mailing list:
“The PostgreSQL OLEDB Provider does not support rowsets, which ArcGIS and other commercial software look for in a data source. That’s why you can establish a connection, but it will always look empty to ArcGIS, regardless of whether you’re trying to load spatial or non-spatial data.
I am just about to finish an extension to ArcMap that loads spatial and non-spatial data from PostGIS and PostgreSQL (as well as other databases) into ArcMap. It does not use a live OLEDB connection, but caches data in local scratch workspaces (personal geodatabase, i.e., Microsoft Jet format).”
