    Description:
    
    The documentation states that 
    
    > There are five methods that an index operator class for GiST must provide,
    and five that are optional.
    
    although there are 11 of them. Eleventh optional sortsupport method was
    added in 16fa9b2b30a.

    Hmm, that's pretty broken all right, but it was broken before too.
    According to Table 38.11, there are "ten support functions, three of
    which are optional".  So there have been repeated documentation
    failures in this area.  I notice that the two lists don't agree
    on what the "equal" support function is called, either.
    
    Will fix, thanks for noticing!
