Pavel,

just a question. Why should it be necessary to add explicit typcasting here? I can't see
the problem in more depth. I still think that the function is called with the wrong
parameter. Would be cool to hear your points to understand the problem better ;-)

Another idea to be sure that the function is working correctly is to call the function in
psql and see if an error is thrown ... if yes its a paramter problem. If no its an
external problem (I think this is called by a Java app ... isn't it?).

Cheers

Andy
