Log message:
    Extend join-selectivity API (oprjoin interface) so that join type is
    passed to join selectivity estimators.  Make use of this in eqjoinsel
    to derive non-bogus selectivity for IN clauses.  Further tweaking of
    cost estimation for IN.
    initdb forced because of pg_proc.h changes.
