Excellent, thanks, that's a big improvement to those docs all around. I
should have checked the latest before posting, almost everything I
mentioned was already addressed.

There's still one very minor thing:

"A GiST index is lossy, meaning it is necessary to check the actual
table row to eliminate false matches."

could be changed to something like:

"A GiST index is lossy, meaning that the index may produce false
matches, and it is necessary to check the actual table row before
eliminating these false matches.

And perhaps change:

"Lossiness causes performance degradation since random access to table
records is slow; ..."

to something like:

"Lossiness causes performance degradation due to unnecessary random
accesses to table records; ..."

The only reason I say this is because, on my first reading, I read that
to mean that lossless indexes don't require trips to the heap at all
(which isn't true, yet).
