            geometry_gist_sortsupport_2d (internal);

_ST_DumpPoints removed, was no longer needed after PostGIS 2.1.0 when ST_DumpPoints got reimplemented in C

B-Tree index operators < = > changed to provide better spatial locality on sorting and have expected behavior on GROUP BY. If you have btree index for geometry or geography, you need to REINDEX it, or review if it was created by accident and needs to be replaced with GiST index. If your code relies on old left-to-right box compare ordering, update it to use << >> operators.

Important changes

Starting with this version offline raster access and use of GDAL drivers are disabled by default.

A.58. Release 2.0.0

Release date: 2012/04/03

This is a major release. A hard upgrade is required. Yes this means a full dump reload and some special preparations if you are using obsolete functions. Refer to Section 3.4.2, “Hard upgrade” for details on upgrading. Refer to Section 15.12.12, “PostGIS Functions new, behavior changed, or enhanced in 2.0” for more details and changed/new functions.

Testers - Our unsung heroes

We are most indebted to the numerous members in the PostGIS community who were brave enough to test out the new features in this release. No major release can be successful without these folk.

Below are those who have been most valiant, provided very detailed and thorough bug reports, and detailed analysis.

Andrea Peri - Lots of testing on topology, checking for correctness
Andreas Forø Tollefsen - raster testing
Chris English - topology stress testing loader functions
Salvatore Larosa - topology robustness testing
Brian Hamlin - Benchmarking (also experimental experimental branches before they are folded into core) , general testing of various pieces including Tiger and Topology. Testing on various server VMs
Mike Pease - Tiger geocoder testing - very detailed reports of issues
Tom van Tilburg - raster testing

Important / Breaking Changes

http://trac.osgeo.org/postgis/ticket/722, http://trac.osgeo.org/postgis/ticket/302, Most deprecated functions removed (over 250 functions) (Regina Obe, Paul Ramsey)

Unknown SRID changed from -1 to 0. (Paul Ramsey)

— (most deprecated in 1.2) removed non-ST variants buffer, length, intersects (and internal functions renamed) etc.

— If you have been using deprecated functions CHANGE your apps or suffer the consequences. If you don’t see a function documented — it ain’t supported or it is an internal function. Some constraints in older tables were built with deprecated functions. If you restore you may need to rebuild table constraints with populate_geometry_columns(). If you have applications or tools that rely on deprecated functions, please refer to Q: 9.2 for more details.

http://trac.osgeo.org/postgis/ticket/944 geometry_columns is now a view instead of a table (Paul Ramsey, Regina Obe) for tables created the old way reads (srid, type, dims) constraints for geometry columns created with type modifiers reads rom column definition

A.84. Release 1.0.3

Release date: 2005/08/08

Contains some bug fixes - including a severe one affecting correctness of stored geometries - and a few improvements.

Upgrading

Due to a bug in a bounding box computation routine, the upgrade procedure requires special attention, as bounding boxes cached in the database could be incorrect.

An hard upgrade procedure (dump/reload) will force recomputation of all bounding boxes (not included in dumps). This is required if upgrading from releases prior to 1.0.0RC6.

If you are upgrading from versions 1.0.0RC6 or up, this release includes a perl script (utils/rebuild_bbox_caches.pl) to force recomputation of geometries' bounding boxes and invoke all operations required to propagate eventual changes in them (geometry statistics update, reindexing). Invoke the script after a make install (run with no args for syntax help). Optionally run utils/postgis_proc_upgrade.pl to refresh postgis procedures and functions signatures (see Soft upgrade).

Bug fixes

Severe bugfix in lwgeom’s 2d bounding box computation

Bugfix in WKT (-w) POINT handling in loader

Bugfix in dumper on 64bit machines
