Log message:
    Using canonicalize_qual() to get rid of duplicate index predicate
    conditions is overkill; set_union() does the job about as well, and
    much more efficiently.  Furthermore this avoids assuming that
    canonicalize_qual() will check for duplicate clauses at all, which
    it may not always do.
