Description

The simplest spatial aggregation once both points and shapes are supported is ST_EXTENT. This is also the only aggregation being considered for non-licensing due to its potential usage in Kibana. The function is similar to ST_ENVELOPE, but instead of generating the bounds for a geometry argument, it aggregates over all geometries for that field, and produces a combined bounding box.
