Hi Tom,
Yes, we start seeing this ERROR after upgrade to 9.1.7. The ERROR is from the
"cluster jms_messages" command. Last night, the ERROR happened three times:
(1) at 00:20:01
ERROR: missing chunk number 0 for toast value 1239124 in pg_toast_35328
(2) at 00:25:01
ERROR: missing chunk number 0 for toast value 1239124 in pg_toast_35328
(3) at 00:35:01
ERROR: missing chunk number 0 for toast value 1241022 in pg_toast_35328
The "cluster jms_messages" runs every 5 minutes. However, so far, it seems that
the ERROR happens at about mid-night and 35328 is the toast area of the
"jms_message" table:
-[ RECORD 1 ]-+-------------
oid | 35328
relname | jms_messages
reltoastrelid | 35331
reltoastidxid | 0
Thanks a lot,
Pius

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?
