PostGIS 3.0.0alpha1

Author: Regina Obe 2019/05/26 in news ( release, 3, 3.0.0alpha1 )

The PostGIS development team is pleased to release PostGIS 3.0.0alpha1.

This release works with PostgreSQL 9.5-12beta1 and GEOS >= 3.6

Best served with PostgreSQL 12beta1.

3.0.0alpha1

Note that a major change in 3.0 is that the raster functionality has been broken out as a separate extension. If you are upgrading from a previous edition, do the following:

After installing the binaries or after running pg_upgrade, make sure to do:

ALTER EXTENSION postgis UPDATE;
-- this next step repackages raster in its own extension
-- and upgrades all your other related postgis extension
SELECT PostGIS_Extensions_Upgrade();
 
--if you don't use raster, you can do
DROP EXTENSION postgis_raster;

— New users

CREATE EXTENSION postgis;
CREATE EXTENSION postgis_raster;
CREATE EXTENSION postgis_topology;
CREATE EXTENSION postgis_tiger_geocoder;

If you use legacy.sql or legacy_minimal.sql, make sure to rerun the version packaged with these releases.

PostGIS 3.1.1

The PostGIS Team is pleased to release the release of PostGIS 3.1.1!

This release is a bug fix release, addressing issues found in the previous 3.1 release.

#4814, Crash passing collection with only empty components to ST_MakeValid
#4818, Make the VSICURL synthetic driver work as documented
#4825, Unstable results from ST_MakeValid
#4823, Avoid listing the same geometry in different collections

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.
