View all closed tickets for 3.0.0.
Note that a major change in 3.0 is that the raster functionality has been broken out as a separate extension. If you are upgrading from a previous edition, do the following:
After installing the binaries or after running pg_upgrade, make sure to do:
ALTER EXTENSION postgis UPDATE; -- this next step repackages raster in its own extension -- and upgrades all your other related postgis extension SELECT PostGIS_Extensions_Upgrade(); --if you don't use raster, you can do DROP EXTENSION postgis_raster;
– New users
CREATE EXTENSION postgis; CREATE EXTENSION postgis_raster; CREATE EXTENSION postgis_topology; CREATE EXTENSION postgis_tiger_geocoder;
If you use legacy.sql or legacy_minimal.sql, make sure to rerun the version packaged with these releases.
