As  proposed,  here  is  the current version of PL/pgSQL. The
    test isn't that complete up to now,  but  I  think  it  shows
    enough of the capabilities of the module.

    The  Makefile  assumes  it  is  located  in a directory under
    pgsql/src/pl.   Since   it   includes   Makefile.global   and
    Makefile.port  and doesn't use any own compiler/linker calls,
    it should build on most of our supported  platforms  (I  only
    tested  under Linux up to now).  It requires flex and bison I
    think. Maybe we should ship prepared gram.c etc. like for the
    main parser too?
