hi all:

In Document "Table 59-1. Built-in GiST Operator Classes":

"range_ops any range type && &> &< >> << <@ -|- = @> @>"， exist double "@>"，

 

Should be "<@ @>" ?

It helps to reference the current version of the page (or provide a url link) as that section seems to have migrated to Chapter 64 - though it is unchanged even on the main development branch.

The table itself is extremely difficult to read: it would be more easily readable if the font was monospaced, but its not.

I'm reasonably confident that the equal sign is part of the second-to-last operator while the lone @> is the final operator.  Mostly I say this because GiST doesn't do straight equality so a lone equal operator isn't valid.
