[postgis-users] st_geometryn

[Bob Pawley]

Yes.

But how does it determine which is the first geometry.

I've been using it on multipoints and in those cases the first point is on 
the left with the horizontal plane and the bottom with the vertical.

Hi Bob,
I'm not sure to understand your question:
st_geometryN will return the Nth geometry from a collection, counting at 1.
