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:

1ALTER EXTENSION postgis UPDATE;
2-* this next step repackages raster in its own extension
3-* and upgrades all your other related postgis extension
4SELECT PostGIS_Extensions_Upgrade();
5
6--if you don't use raster, you can do
7DROP EXTENSION postgis_raster;

-* New users

1CREATE EXTENSION postgis;
2CREATE EXTENSION postgis_raster;
3CREATE EXTENSION postgis_topology;
4CREATE EXTENSION postgis_tiger_geocoder;

If you use legacy.sql or legacy_minimal.sql, make sure to rerun the version packaged with these releases.
