At least, that's what Pythagoras told me once :)<br>

Hey guys, weird results here...<br>
<br>
Check this:<br>
<br>
SELECT ST_MaxDistance(<br>
ST_MakeLine(ST_MakePoint(0,0),<u></u>ST_MakePoint(1,1)),<br>
ST_MakeLine(ST_MakePoint(0,0),<u></u>ST_MakePoint(-1,-1)));<br>
-- 2.82842712474619 (this corresponds to 2x sqrt(2)?)<br>
<br>
For me the max distance between these polylines is 2.<br>
<br>
Or am I expecting something diferent for this function?<br>
<br>
Thanks<br>
