[postgis-users] Partitioning using Geometry

[Brian M Hamlin]

I have implemented this in the past, with "millions of features" ... 
for land use classification in California.. 
given a reference topological set.. each polygon in the topology gets 
an ID, each POINT is assigned to one and only one poly ID
partition on the poly *id* -- no geometry expression in the check constraints

Improvements to the method include weighting, and combining sparse buckets
worked great ..   -Brian
