PostGIS 1.5.8 Manual304 / 310A.29.3ImprovementsDocumentation improvementsMore robust selectivity estimatorMinor speedup in distance()Minor cleanupsGiST indexing cleanupLooser syntax acceptance in box3d parserA.30 Release 1.0.3Release date: 2005/08/08Contains some bug fixes - including a severe one affecting correctness of stored geometries - and a few improvements.A.30.1UpgradingDue to a bug in a bounding box computation routine, the upgrade procedure requires special attention, as bounding boxes cachedin the database could be incorrect.An hard upgrade procedure (dump/reload) will force recomputation of all bounding boxes (not included in dumps). This isrequired 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 forcerecomputation of geometries’ bounding boxes and invoke all operations required to propagate eventual changes in them (geometrystatistics update, reindexing). Invoke the script after a make install (run with no args for syntax help). Optionally runutils/postgis_proc_upgrade.pl to refresh postgis procedures and functions signatures (see Soft upgrade).A.30.2Bug fixesSevere bugfix in lwgeom’s 2d bounding box computationBugfix in WKT (-w) POINT handling in loaderBugfix in dumper on 64bit machinesBugfix in dumper handling of user-defined queriesBugfix in create_undef.pl scriptA.30.3ImprovementsSmall performance improvement in canonical input functionMinor cleanups in loaderSupport for multibyte field names in loaderImprovement in the postgis_restore.pl scriptNew rebuild_bbox_caches.pl util scriptA.31 Release 1.0.2Release date: 2005/07/04Contains a few bug fixes and improvements.
