Hi, thanks for the patch.
I think this sentence is a bit confusing:

The new text seems to say that one of the seven support funcs is
optional, which is wrong if I correctly understand that the "fetch"
optional function was added.
Maybe "GiST indexes require nine support functions, two of which are
optional, as shown in XYZ".
This is to be backpatched as far back as commit d04c8ed9044ec, right?
