Do you mean that you want to read postgis data with mapserver?
Perhaps this will help

You should file a ticket on it... I think if you create a function

should get around your casting problem.
CREATE OR REPLACE FUNCTION geography(bytea)
RETURNS geography
AS 'SELECT ST_GeogFromWKB($1)'

Nicolas,
Is the select used to create the view returning rows ?
yes, I want to get the intersected parts of the polygonlayer and the area (I
need the returned rows in a php application)
Is this IsEmpty test necessary to validate there is an intersection ?
yes, because I want only the inters

I've been using Google Talk and thought you might like to try it out.
We can use it to call each other for free over the internet. Here's an
invitation to download Google Talk. Give it a try!

I have a polygon table (alk_flurstuecke) and create a view with a 40-meter
