ST_SetSRID downcasts MultiPolygon to Polygon #109
Description
Hi guys,
I am not sure if this is a bug or a feature, however in my opinion this behavior is surprising.
SELECT ST_AsText(
ST_MultiPolygon(array(0.0, 0.0, 1.0, 0.0, 1.0, 1.0, 0.0, 1.0))
) FROM src LIMIT 1;
> OK
> MULTIPOLYGON (((0 0, 0 1, 1 1, 1 0, 0 0)))
> Time taken: 1.156 seconds, Fetched: 1 row(s)
vs
SELECT ST_AsText(
ST_SetSRID(ST_MultiPolygon(array(0.0, 0.0, 1.0, 0.0, 1.0, 1.0, 0.0, 1.0)), 4326)
) FROM src LIMIT 1;
> OK
> POLYGON ((0 0, 0 1, 1 1, 1 0, 0 0))
> Time taken: 0.916 seconds, Fetched: 1 row(s)
Best, Christoph
