Hello everybody,
after upgrading from geoserver 2.11 to geoserver 2.22, we have a few postgis
layers that refuse to render in the preview.
Here is a simplified example, in postgis:
create table testhy(
geometry geometry constraint enforce_dims_the_geom check
(st_ndims(geometry) = 4)
);
We get this exception:
Caused by: java.lang.IllegalArgumentException: Output dimension must be 2 or 3

org.geotools.jdbc.JDBCFeatureSource.getReaderInternal(JDBCFeatureSource.java:609)
I browsed the code. geoserver gets dimension 4 based on a variant of this
query (PostGISDialect.java):
SELECT * FROM GEOMETRY_COLUMNS WHERE coord_dimension not in (2,3);
but the query generated by geoserver to fetch the data is :
SELECT ST_AsBinary(ST_Force2D("geometry")) as "geometry" FROM "public"."testhy"
WHERE […]
Note the ST_Force2D that removes the Z and M dimension, so there are only 2
dimensions, not 4.
