Comment(by strk):

 Alright, the return datatype changed, which is the reason why the function
 is dropped.
 BUT, we should make the drop dependent on source version, driven by
 postgis_proc_upgrade.pl.

 When a function signature changed in an way that is not compatible with
 "CREATE OR REPLACE FUNCTION", we should note it with a "Last Something"
 documenting the incompatibility.
