You still need to avoid conflicting name assignments, so my
recommendation would really be to use the select-a-new-name code already
in use for CREATE INDEX without an index name. The underscore idea is
cute, but I doubt it's worth the effort to implement, document, or
explain it in a way that copes with repeated REINDEXes and conflicts.
