Assuming that the bug doesn't get fixed and you decide to switch technologies, PostgreSQL+PostGIS[0] is worth considering. Switching will also open up other GIS tools for your use, like QGIS[1], which may be useful.

I'm using PostgresSQL+PostGIS with QGIS as the front-end for a personal project and it's been fantastic.
