PostGIS 2.0.0
2012/04/03
* Important / Breaking Changes *
- Upgrading to PostGIS 2.0 REQUIRES a dump and restore. See the
"Hard Upgrade" section of the documentation.
- Functions deprecated during the 1.X series (mostly non-ST variants)
have been removed. Update your application to the new signatures.
If you cannot update your application, see the legacy.sql file
to enable the old signatures.
- GEOMETRY_COLUMNS is now a view, not a table. Code that manually
updates the table must be changed to either use the management
functions (eg AddGeometryColumn) or the new geometry typmod options
(eg CREATE TABLE t (g GEOMETRY(Polgyon, 4326)))
- ST_AsBinary and ST_AsText now return 3D/4D results in ISO SQL/MM
format when called on 3D/4D features.
- The "unknonwn SRID" is now 0, not -1.
(eg ST_SRID(ST_GeomFromText('POINT(0 0)')) returns 0)
- ST_NumGeometries returns 1 for singletons. ST_GeometryN returns the
the geometry for singletons.
- probe_geometry_columns(), rename_geometry_table_constraints(),
fix_geometry_columns(), have been removed since GEOMETRY_COLUMNS
is now a view.
- 3D analysis functions are now named with "3D" as a prefix
instead of a suffix (eg ST_Length3D has become ST_3DLength)
- Operator && does not check for SRID mismatch anymore
