<p class="MsoNormal">We would require that msPostGISLayerGetExtent would apply the specified filter when calculating the layer extent. This would probably be happen by appending the "where" clause from msPostGISBuildSQLWhere to sqlExtentTemplate. Does this
make sense?<br>
<br>
I've checked the code and some of the drivers consider the filter and some are not, so I'm not completely sure about the expected behaviour.<o:p></o:p></p>
