Comment (by mwtoews):

 As a workaround for FDO users that use the PostGIS Provider, you can try
 replacing one of the functions:
 {{{
 CREATE OR REPLACE FUNCTION estimated_extent(text, text, text)
   RETURNS box2d AS
 $BODY$DECLARE
   res box2d;
 BEGIN
   EXECUTE 'select st_extent(' || quote_ident($3) || ') from ' ||
 quote_ident($1) || '.' || quote_ident($2) INTO res;
   RETURN res;
 END;$BODY$
   LANGUAGE 'plpgsql' IMMUTABLE STRICT SECURITY DEFINER
   COST 1;
 }}}

 This workaround has made AutoCAD Map3D 2008 and 2010 more stable (fewer
 crashes) when loading layers and generally working with the FDO PostGIS
 Provider.
