We put in a change about that last month:

https://git.postgresql.org/gitweb/?p=postgresql.git&a=commitdiff&h=756349c87

Although that hasn't yet propagated to any released branches,
you can see it in the "devel" version of that documentation page:

Hm, I agree that the options part doesn't accept "&", but I don't see
anything preventing use of a "?" there.
