The PostGIS development team is happy to release patch for PostGIS 2.1, the 2.1.6 release. As befits a patch release, the focus is on bugs, breakages, and performance issues. Users with large tables of points will want to priorize this patch, for substantial (~50%) disk space savings.
PostGIS is an extension to the PostgreSQL object-relational database system which allows GIS (Geographic Information Systems) objects to be stored in the database. PostGIS includes support for GiST-based R-Tree spatial indexes, and functions for analysis and processing of GIS objects.
The new release is coming with enhancements to previous version of PostGIS 2.1:
- Ensure edge splitting and healing algorithms use indexes
- Speed up geometry simplification (J.Santana @ CartoDB)
- Speep up geometry type reading (J.Santana @ CartoDB)
The new release also have bug fixes and provide better environment for users:
- Allow geography columns with SRID other than 4326
- Small objects getting inappropriately fluffed up w/ boxes
- Have postgis_typmod_dims return NULL for unconstrained dims
- Allow duplicate points in JSON, GML, GML ST_GeomFrom* functions
- Fix ND-GiST picksplit method to split on the best plane
- Make operators <-> and <#> available for PostgreSQL < 9.1
- Fix dimensionality confusion in &&& operator
- Allow unregistering layers of corrupted topologies
- Avoid exceptions from TopologySummary
- ST_AddBand out-db bug where height using width value
- Allow restore of Geometry(Point) tables dumped with empties in them
