Re: BUG #7819: missing chunk number 0 for toast value 1235919 in pg_toast_35328

Yes, I did not see this ERROR before the upgrade.

Thanks,

Are you saying this error started to appear just after the upgrade? Or
was it there before?

Is that error coming from the CLUSTER operations, or other commands? Is
it persisting across (successful) CLUSTERs? Is it always the same toast
value OID that's being complained of?
