Re: [HACKERS] Synchronous replication

[Heikki Linnakangas]

I wonder if we can continue to rely on the pg_sleep() loop for sleeping 
in walsender. On those platforms where interrupts don't interrupt sleep, 
sending the signal is not going to promptly wake up walsender. That was 
fine before, but any delay is going to be poison to synchronous 
replication performance.

Thoughts?
