You really think this:

    Previous fix for "x FULL JOIN y ON true" failed to handle the case
    where there was also a WHERE-clause restriction that applied to the
    join.  The check on restrictlist == NIL is really unnecessary anyway,
    because select_mergejoin_clauses already checked for and complained
    about any unmergejoinable join clauses.  So just take it out.

is preferable to something like

?  It's not hard to offer an option for that, I guess, but I foresee an
argument about what the default is going to be.
