PostGIS 2.5.0beta1

Author: Regina Obe 2018/07/03 in news ( release, 2.5, 2.5.0beta1 )

The PostGIS development team is pleased to release PostGIS 2.5.0beta1.

This release is a work in progress. No more api changes will be made from this point on before 2.5.0 release. Remaining time will be focused on bug fixes and documentation for the new functionality and performance enhancements under the covers. Although this release will work for PostgreSQL 9.4 and above, to take full advantage of what PostGIS 2.5 will offer, you should be running PostgreSQL 11beta2+ and GEOS 3.7.0beta1 which were released recently.

Best served with PostgreSQL 11beta2 which was recently released.

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

ALTER EXTENSION postgis UPDATE;

— if you use the other extensions packaged with postgis — make sure to upgrade those as well

ALTER EXTENSION postgis_sfcgal UPDATE;
ALTER EXTENSION postgis_topology UPDATE;
ALTER EXTENSION postgis_tiger_geocoder UPDATE;

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.

PostGIS 3.1.0rc1

The PostGIS Team is pleased to release the release candidate of the upcoming PostGIS 3.1.0 release. This version is exposes some of the new performance and feature enhancements in GEOS 3.9 as well as numerous speed enhancements not requiring newer GEOS.
