This is a security release.
Starting with this version offline raster access and use of GDAL drivers are disabled by default.
An environment variable is introduced to allow for enabling specific GDAL drivers: POSTGIS_GDAL_ENABLED_DRIVERS. By default, all GDAL drivers are disabled
An environment variable is introduced to allow for enabling out-db raster bands: POSTGIS_ENABLE_OUTDB_RASTERS. By default, out-db raster bands are disabled
The environment variables must be set for the PostgreSQL process, and determines the behavior of the whole cluster.

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 2.9.2, “Hard upgrade” for details on upgrading. Refer to Section 13.11.1, “PostGIS Functions new, behavior changed, or enhanced in 2.0” 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.

This is a Minor release, containing many improvements and new things. Most notably: build procedure greatly simplified; transform() performance drastically improved; more stable GEOS connectivity (CAPI support); lots of new functions; draft topology support.
It is highly recommended that you upgrade to GEOS-2.2.x before installing PostGIS, this will ensure future GEOS upgrades won't require a rebuild of the PostGIS library.
This release includes code from Mark Cave Ayland for caching of proj4 objects. Markus Schaber added many improvements in his JDBC2 code. Alex Bodnaru helped with PostgreSQL source dependency relief and provided Debian specfiles. Michael Fuhr tested new things on Solaris arch. David Techer and Gerald Fenoy helped testing GEOS C-API connector. Hartmut Tschauner provided code for the azimuth() function. Devrim GUNDUZ provided RPM specfiles. Carl Anderson helped with the new area building functions. See the credits section for more names.
If you are upgrading from release 1.0.3 or later you DO NOT need a dump/reload. Simply sourcing the new lwpostgis_upgrade.sql script in all your existing databases will work. See the soft upgrade chapter for more information.

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).
