[mapserver-users] Trouble querying PostGIS layer

I'm having trouble doing an attribute query on a PostGIS layer. The
data in this layer was formerly in shapefile, and the query worked fine
with it. But with the PostGIS layer, I get no results.
The PHP MapScript query uses a setFilter on the layer, then does a
queryByRect, again, with no results.
The problem appears to be connected to the extent and/or projection.
With the original shapefile, I can echo back the extent rectangle:
[minx] => 342764.988407 [miny] => 4759515.50711 [maxx] => 647042.41629
[maxy] => 5245337.46493 )
--Which is what I'd expect. But with the PostGIS layer, if I echo back
the extent, here is what I get:
[minx] => -3.40282346639E+38 [miny] => -3.40282346639E+38 [maxx] =>
3.40282346639E+38 [maxy] => 3.40282346639E+38
The PostGIS layer is set for the proper SRID, and the correct EPSG and
extent are in the map file.
What is going wrong here?
