Bbox in GetCapabilies for PostGIS layer

The postgis implementation in MapServer may not support reading the real 
data extents automatically (I just don't know), but you should be able 
to set the ows_extent metadata in your layer to tell MapServer which 
extents to use for the BoundingBox in capabilities. By default if 
ows_extent is not specified then MapServer tries to get the extents from 
PostGIS and it seems that it returns something that's way larger than 
the actual data.
