WMS getcapabilities wrong BoundingBox for PostGIS layers

[H åvard Tveite]

In 4.2.5 and 4.4 (todays nightly build), a WMS GetCapabilities request
returns a strange BoundingBox (and LatLonBoundingBox) for PostGIS layers.
For Shape format layers the correct BoundingBox is returned.
My request uses: "&version=1.1.1&request=GetCapabilities"

For my Shape format layers the following is returned (seemingly correct):
<LatLonBoundingBox minx="-0.460251" miny="0" maxx="30.8616" maxy="70.9096"/>
<BoundingBox SRS="EPSG:32633" minx="-77665" miny="0" maxx="1.0934e+06"
maxy="7.86732e+06"/>

For all my PostGIS layers the following is returned:
<LatLonBoundingBox minx="-171.507" miny="-8.2419e+12" maxx="179.211"
maxy="8.2419e+12"/>
<BoundingBox SRS="EPSG:32633" minx="-2.5e+07" miny="-2.5e+07" maxx="2.5e+07"
maxy="2.5e+07"/>

Is this expected behaviour?

In geometry_colums, the srid is 32633 and all the geometries have SRID=32633.

The layers cover approximately the same area.

msPOSTGISLayerGetExtent does not want to check the actual data and sets minx
to -1*FLT_MAX and maxx to FLT_MAX.
How can I help Mapserver determine the bounding box of a PostGIS layer?
I was hoping it would be possible to give mapserver a hint? Something like
specifying EXTENT for the LAYER?
Is there a OWS/WMS parameter for this?
