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I noted that the corresponding wording for GIN indexes was a bit out
of date too :-(.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