 Maybe I'm doing something worng but when I run the following query:

 '''select ST_GeometryN(geom, generate_series(1,ST_NumGeometries(geom))'''

 I receive a single, empty, result when geom is not a multi-geometry.
 I would expect it to returned the same, single, geometry in case it is not
 multi.
 I have a table with both multi and geom. In such case I have to force to
 multi with this:

 '''select ST_GeometryN(''multi''(geom),
 generate_series(1,ST_NumGeometries(''multi''(geom)))'''

 but it is a useless overhead...
