Subject: session waiting IO while background writer writing data
Date: Mon, 14 Apr 2025 13:30:07 +0800
Message-ID: <CAHgTRfd4kwVBgQ5Pc+i+CRTRaWm1y7wGpZMyMEbfdyjG7bGKVg@mail.gmail.com> (raw)

   pgv14.8 , we found all session waiting on "DataFileWrite", and at the
same time, background writer is doing IO and waiting on "DataFileWrite". Is
it possible to see "background writer" block or impact user sessions IO
"DatafileWrite" if both running at the same time ?

Thanks,

James
