Hi,
At the end of the handshake for replication, a CopyOutResponse
message might not arrive at the standby for a while if there is
no WAL record to send. Also walreceiver would get stuck until
that message has arrived. This is not a big problem, but should
be fixed.
The cause is that walsender

The Linux kernel had a big push to reduce latency, and one of the
tricks they did was they replaced the usual interrupt points with a
call which noted how long it had been since the last interrupt point.
It occurs to me we could do the same for CHECK_FOR_INTERRUPTS() by
conditionally having it

Yeah, they do.
Do you think there's an advantage to having something that is
hash-specific a la the btree-specific stuff we already have?
Sure: it'll be more efficient

Hi,
Since we insert a new entry into the index for every update that's being
made into the table, we inevitably make a unique check against the older
version of the newly inserted row, even when the values are not updated. Of
course i am talking about non-HOT updates. (We will not go to the
