Andrew,
Alexander Korotkov is an author of hash_ops ! I think he should be
granted. I wrote "Alexander Korotkov introduced an elegant hash
opclass for GIN, which competes with MongoDB performance in contains
operator".

PS.
Actually, it happened in Dublin, in the night before our
presentation. I was a bit upset to learn that MongoDB index performs
better than our GIN and was thinking in the background, what to say in
presentation. I and Alexander decided to walk in seaside, where I got
hashing idea, which Alexander also thought about. He quickly
implemented in the hotel, while we were waiting our food (at night !)
and first experiments shown the better than MongoDB performance !
After several rounds the code was accepted by Teodor and now is
shining in jsonb.
Oops. Apologies to Alexander - I should have listed him as an author.
We'll make sure he gets credit in the release notes.
cheers
andrew
