PostGIS 2.3.0 Released

Sep 26, 2016 release 2.3

The PostGIS development team is pleased to announce the release of PostGIS 2.3.0. This is the first version to utilize the parallel support functionality introduced in PostgreSQL 9.6. As such, if you are using PostgreSQL 9.6, we strongly encourage you to use this version.

Parallel support will make many queries using PostGIS relationship operators and functions faster. In order to take advantage of parallel query support, make sure to set max_parallel_workers_per_gather to something greater than 0 as noted in max_parallel_workers_per_gather PostgreSQL runtime configs

Best served with [PostgreSQL 9.6+] which is due out this week and pgRouting 2.3.0 which also just got released.

Packages from maintainers will be out in the coming days and weeks.

If you are a Mac user using newer XCode 8, you might run into some compilation issues as a result of recent changes in XCode. Refer to https://trac.osgeo.org/postgis/ticket/3643 for a patch you can use.

Please report bugs that you find in this release.
