Yepp - PL/pgSQL has it's own scanner/parser (i.e.
flex/bison). The tricky part in this case is that the
languages object file will be loaded at runtime into the
backend, where the main scanner/parser is already present.
Thus I'm mangling with sed(1) over the generated sources to
avoid global symbol conflicts.
