    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.
