scanner/parser for FOREIGN KEY

Hi,

    we  still need the enhancement of the scanner/parser combo to
    enable FOREIGN KEY specification as  column  constraint  (the
    due to shift/reduce disabled NOT DEFERRABLE part).

    IMHO this must be done before going into BETA.  As discussed,
    a little token lookup/queueing between lex and  yacc  can  do
    the  trick. I'd like to add a slightly generic method for it,
    so the lookahead function can be reused if we  sometimes  get
    trapped again with a similar problem.

    Do we have a consensus to implement it that way now?
