- anarazel 9y ago> Is the hash guaranteed to be unique though? There is always a possibility of a hash collision I mean my point is that hashindexes do not support uniqueness right now. But hash collisions wouldn't be a problem there. Does mainly require some tricky concurrency aware code (consider cases lik ewhere one transaction just deleted a conflicting row but is still in progress, and a new value like that is inserted, etc).
