<div>I have looked a little at this #294 thing about empty geometries cases</div>
<div> </div>
<div>I think some strategy is needed to manage that one because it is big and will need a lot of different discussions I can imagine.</div>
<div>I have looked through a lot of the functions of today, what they give with empty geometries and found some inconsistencies for example:</div>
<div>select ST_NumPoints('POLYGON EMPTY') returns nothing, while</div>
<div>select ST_NPoints('POLYGON EMPTY') returns 0<br />
</div>
<div>I think we in the end will need a matrix with the behavior in different cases with different versions. </div>
<div>Should that be a part of documentation or wiki?</div>
