It was trying to interpret a pointer-to-character-string as
a pointer to a Node, so the results would be quite machine-
dependent.  This didn't have any effect on execution of the
query, only on display of the parsetree in the postmaster log;
but in the worst-case scenario you could see a coredump from
the printout routine following a nonaligned pointer or some such.

Fixed for 7.0.1.
