EDB PostGIS is a PostgreSQL extension that allows you to store Geographic Information Systems (GIS) objects in an Advanced Server database. It includes functions for analyzing and processing GIS objects and support for GiST-based R-Tree spatial indexes.
The complete documentation for PostGIS is added to your system during the installation and is available online at the PostGIS project site.
This release contains a merge with upstream, which includes the following bug fixes:
- Improved handling of more complex compound coordinate systems.
- The SRID in TopoGeometry is fixed for empty geometry objects.
- Improved message when no zip code is provided for
- Axis flips are now done for a CRS when
Latis set as the first column. In other cases, EPSG database order is used.
- Support recent Proj versions that have removed
- The tolerance is now adjusted to improve geodetic calculations.
- Fix on improper conversion of negative geographic azimuth to positive.
- Allow DBSCAN cluster to form when recordset length equal to minPoints.
- Ensure bounding boxes are refreshed after coordinate transforms.
- Fix raster issues related to PostgreSQL 14 tablefunc changes.
- Update to support Tiger 2020.
- Change Proj cache lifetime to last as long as connection.
For more information, please refer to the Upstream release notes.
To upgrade from PostGIS version 2.5.4 (or lower) to 3.1.2, you must perform the following actions:
- Since the return type of the raster functions have changed, you must drop and re-create the raster extension as part of the upgrade process.
- Before upgrading to version 3.1.2, you must upgrade to 3.1.1 first as an intermediate step.
- When the PostGIS data has a dependency on the raster functions, upgrading to PostGIS 3.1.2 requires dumping and reloading the data.
See the upgrade section for details.
