[postgis-users] Computing a centroid on GEOGRAPHY objects

I have a huge bunch of scattered lat/long coordinates stored as GEOGRAPHY
type. I would now like to cluster some of them and
compute their centroids.
I know there is a centroid computation function in Postgis, but it seems to
only work on a geometry type.
The lat/long coordinates are spread all across the globe and hence I cannot
convert it to local UTM formats because there is a discrepancy when going
across different zones!
