PostGIS 3.1.0

The PostGIS Team is pleased to release the release of PostGIS 3.1.0!

This version exposes the new features of GEOS 3.9 as well as numerous core performance enhancements for spatial joins, large object access, text format output and more.

Performance is a key feature of this release, with improvements to spatial joins, text outputs, large object reads, vector tile output, and a host of smaller tweaks.

The k-means clustering code has been enhanced to support weighting and higher dimensional clusters.

Geometry generators to create hexagonal and square tilings have been added, for simpler in-the-database summarization queries.

Finally, PostGIS exposes the latest enhancements in the GEOS geometry library 3.9 version. The new overlay engine (aka “OverlayNG”) provides more robust handling of difficult input geometries, using a set of new noding strategies to process geometry. For the end user, this should mean no more “topology exceptions” when using the union, difference, intersection or symmetric difference functions. PostGIS also exposes the new fixed precision overlay capability via an additional grid-size parameter on ST_Intersection and the other overlay functions.
