Yes, there was. I very nearly came down on the side of making
jsonb_hash_ops the default, but given that it doesn't make all
operators indexable, I ultimately decided against supporting that
course of action. I thought that that would be an odd limitation for
the default GIN opclass to have. It was a very close call in my mind,
and if you favor changing the default now, in light of the few
complaints we've heard, I think that's a reasonable decision. That
said, as I noted in the main -bugs thread, the case presented is
fairly atypical.
