Populate_Geometry_Columns() after your query.
In your case:
However, this will only work for those columns that have the same geometry type for each row. The result of ST_Intersection is often very diverse (e.g. a mix of
ST_GeometryCollection). You may want to use
CREATE TABLE reu_oin_oi2 AS (
(ST_Dump(ST_Intersection (test.geom, eingangsdaten.geom) AS geom2
ST_Intersects (eingangsdaten.geom, b.geom)
test.id = 2
However, be aware that in this way, any intersection between a geom from the eingangsdaten table and a geom from the test table that consists of more than one piece, will result in one than one row in your reu_oin_oi2 table.
