Hi,
In HEAD, OwnLatch can elog during holding the spinlock WalSnd->mutex.
This seems to be unsafe because that elog would cause the walsender
to exit without releasing the spinlock. Because of the spinlock being
held, subsequent walsender would get stuck. I wonder if OwnLatch really
needs to be protected by the spinlock.
Regards,
