[NEW PORT] databases/postgis31: Geographic objects support for PostgreSQL
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
The k-means clustering code has been enhanced to support weighting and higher
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.
NOTA: GEOS 3.9 is not in ports yet.
