----------------------------------

-When upgrading an existing cartodb user database, the cartodb extension
-can be migrated from the "unpackaged" version. The procedure will copy
-the data from ``public.CDB_TableMetada`` to ``cartodb.CDB_TableMetadata``,
-re-cartodbfy all tables using old functions in triggers and drop the
-cartodb functions from the 'public' schema. All new cartodb objects will
-be in the "cartodb" schema.
