Datenbank Postgis von V2.0 to V2.1

[nine]

PostGIS 2.0 has been deprecated - please migrate your databases. The package postgresql-9.1-postgis-2.0-scripts is installed on this system, which means you likely use the PostGIS extension in some databases. Debian is now shipping PostGIS version 2.1 and dropped support for 2.0, meaning bug or security fixes will no longer be provided for the older one. Thus it is strongly recommended to migrate all databases to PostGIS 2.1 as soon as possible. Of course, databases that are already using PostGIS 2.0 will continue to work. Note, however, that with this upgrade it's no longer possible to create version 2.0 of the extension PostGIS. Instead, 'CREATE EXTENSION postgis;' will now give you version 2.1. Note that this also affects backups.
