Until somebody implements Philip's idea, a much simpler approach could
obviate the whole issue:
- Keep the name 'C' for both old-style and new-style module declarations.- Require that new-style modules define a
distinguishedsymbol, such as "int __postgresql_call_7_1;".
The module loader can look for symbols that start with "__postgresql_call"
and adjust automatically, or report an error. This
- Breaks no backward compatibility, - Defines a clear method for handling future changes, to prevent this problem
fromarising again, - Creates no particular inconvenience for writers of modules, and - Might be very easy to
implement.
