Fair enough.

Well how long did we wait for the fix already? The lack of crash safety
and replication ability is not just a drawback, it's about killing the

Maybe we should implement UNLOGGED indexes and then Hash Indexes would
only exist in the UNLOGGED fashion?
But well, yeah ok, my idea is a non-starter.
