    Seems to me like the typmod value given to

        Numeric numeric(Numeric num, int dummy, int32 typmod)

    got  mangled  up  somewhere.  First you should check that the
    atttypmod in pg_attribute for n1.n and n1.d  is  correct.  It
    should have the value

        ((precision << 16) | scale) + 4

    and must be 655369 for a numeric(10,5).

    If   that   isn't   the  case,  you  might  take  a  look  at
    include/nodes/parsenodes.h.   The  typmod  field  of   struct
    TypeName  should  be  of int32 (I changed that shortly before
    moving numeric into the backend).

    If that isn't the error, it would be good if you're a  little
    familiar  with  gdb.  If  so,  set  a  breakpoint on function
    numeric()  and  try  to  find  where   on   it's   way   from
    pg_attribute.atttypmod  to  the  call  to  numeric()  it  got
    mangled up.
