Agreed that timeout makes little sense in this context, and IPC looks
correct.
+ pgstat_report_wait_start(WAIT_EVENT_CHECKPOINT_DELAY_START);
do
{
pg_usleep(10000L); /* wait for 10 msec */
} while (HaveVirtualXIDsDelayingChkpt(vxids, nvxids,
DELAY_CHKPT_START));
+ pgstat_report_wait_end();
HaveVirtualXIDsDelayingChkpt() does immediately a LWLockAcquire()
which would itself report a wait event for ProcArrayLock, overwriting
this new one, no?
