Release Notes 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 for details on upgrading. Refer to for more details and changed/new functions. 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 #722, #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 for more details. #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 #1081, #1082, #1084, #1088 - Mangement functions support typmod geometry column creation functions now default to typmod creation (Regina Obe) #1083 probe_geometry_columns(), rename_geometry_table_constraints(), fix_geometry_columns(); removed - now obsolete with geometry_column view (Regina Obe) #817 Renaming old 3D functions to the convention ST_3D (Nicklas Avén) #548 (sorta), ST_NumGeometries,ST_GeometryN now returns 1 (or the geometry) instead of null for single geometries (Sandro Santilli, Maxime van Noppen) KNN Gist index based centroid (<->) and box (<#>) distance operators (Paul Ramsey / funded by Vizzuality) Support for TIN and PolyHedralSurface and enhancement of many functions to support 3D (Olivier Courtin / Oslandia) Raster support integrated and documented (Pierre Racine, Jorge Arévalo, Mateusz Loskot, Sandro Santilli, David Zwarg, Regina Obe, Bborie Park) (Company developer and funding: University Laval, Deimos Space, CadCorp, Michigan Tech Research Institute, Azavea, Paragon Corporation, UC Davis Center for Vectorborne Diseases) Making spatial indexes 3D aware - in progress (Paul Ramsey, Mark Cave-Ayland) Topology support improved (more functions), documented, testing (Sandro Santilli / Faunalia for RT-SIGTA), Andrea Peri, Regina Obe, Jose Carlos Martinez Llari 3D relationship and measurement support functions (Nicklas Avén) ST_3DDistance, ST_3DClosestPoint, ST_3DIntersects, ST_3DShortestLine and more...

In particular, it fixes a memory leak preventing successful build of GiST indexes for large spatial tables. If you are upgrading from release 1.0.3 you DO NOT need a dump/reload. If you are upgrading from a release between 1.0.0RC6 and 1.0.2 (inclusive) and really want a live upgrade read the upgrade section of the 1.0.3 release notes chapter. Upgrade from any release prior to 1.0.0RC6 requires an hard upgrade. Memory leak plugged in GiST indexing Segfault fix in transform() handling of proj4 errors Fixed some proj4 texts in spatial_ref_sys (missing +proj) Loader: fixed string functions usage, reworked NULL objects check, fixed segfault on MULTILINESTRING input. Fixed bug in MakeLine dimension handling Fixed bug in translate() corrupting output bounding box Documentation improvements More robust selectivity estimator Minor speedup in distance() Minor cleanups GiST indexing cleanup Looser syntax acceptance in box3d parser Release date: 2005/08/08 Contains some bug fixes - including a severe one affecting correctness of stored geometries - and a few improvements. 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).
