<p>This looks odd. Here is what pgAdmin tells me if is the current
definition of st_setsrid (cost of 1.0)<br>
</p>
<p><br>

<p>CREATE OR REPLACE FUNCTION public.st_setsrid(<br>

IMMUTABLE NOT LEAKPROOF STRICT <br>

Bill,<br>
<br>
Never mind. Thanks to Brian Hamlin's nudging on IRC that
he sees the issue<br>
too, I was able to replicate it.<br>
<br>
<br>
I think the reason I missed it in my testing is that it
doesn't happen with<br>
the more common cases of:<br>
<br>
SELECT e.gid<br>
FROM e1 , e2<br>
WHERE ST_Intersects(e1.geom, e2.geom);<br>
<br>
Or where you use constants in ST_MakePoint like your
example<br>
<br>
<br>
But only in case where you have:<br>
<br>
SELECT e.gid<br>
FROM e1 , e2<br>
WHERE ST_Intersects(e1.geom,
ST_SetSRID(ST_MakePoint(e2.longitude,<br>
e2.latitude),4326) );<br>
<br>
<br>
So I'll go ahead and ticket it and try to track down the
root cause. I<br>
suspect it affects all our relation functions.<br>
<br>
Thanks for bringing to our attention,<br>
<br>
Regina<br>
