<div align="left">Hallo</div>
<div align="left"> </div>
<div align="left">ST_Equals is marked as "immutable strict", other functions like ST_Intersects, ST_Within and so on is only marked "immutable"</div>
<div align="left"> </div>
<div align="left">I guess that is why I have problems getting the index used for ST_Equals.</div>
<div align="left"> </div>
<div align="left">Is there a reason for immutable strict on st_equals or is it a mistake?</div>
<div align="left"> </div>
<div align="left">It is the same in trunk and 1.5.1</div>
