Hi Johan,

The issue here is that it is the geometry you are creating on the fly is
constructed with a SRID of -1 because it has not yet been tied to a
coordinate system - your table definition and the constraints that go with
it are fine. The way to handle this is to use setSRID()/GeometryFromText()
to assign the same coordinate system to your polygon when you construct it,

SELECT the_geom FROM reflijst WHERE ((the_geom && GeomFromText(
'POLYGON((33595.443392445566 15067.465440617714, 281187.7093687274
15067.465440617714, 281187.7093687274 254932.5345593823,33595.443392445566
254932.5345593823,33595.443392445566 15067.465440617714))', 103300)))
