That wording seems just as bizarre to me: a support function can hardly
be both "required" and "optional".  After a bit of thought I changed it
to 
    GiST indexes have nine support functions, two of which are optional,

I noted that the corresponding wording for GIN indexes was a bit out
of date too :-(.  Pushed with those corrections.
