Hi all,

We have done all the suggested things from reindex and vaccume to hardware heat issue.

But do not get the clue why this happened?

Can you please suggest what are the checkpoints we follow so that we can avoid this kind of issue in future?

Regards
Tarkeshwar

Hi all,

Finally DB was restored from the backup and the issue was solved.

Is the data corrupted?

I feel that data is corrupted as well as its some of the data dictionary also corrupted.
That is the reason it is not displaying any columns for the table even the table is present.

Regards
Tarkeshwar

Hi,

We performed the following actions to recover

1. Restart the DB
2. Rebuild the index
3. Vacume the index

mgrdb=# select count(*) from mm_activealarm;
ERROR: missing chunk number 0 for toast value 54787 in pg_toast_2619 mgrdb=# REINDEX table pg_toast.pg_toast_2619; REINDEX mgrdb=# VACUUM ANALYZE mm_activealarm; VACUUM mgrdb=# commit;
WARNING: there is no transaction in progress COMMIT mgrdb=# select count(*) from mm_activealarm;
ERROR: missing chunk number 0 for toast value 54787 in pg_toast_2619 mgrdb=#

4. Finally we drop the MM_ActiveAlarm table.and recreated it 5. Still after that we were not able to see the column even after recreating the table with columns there are no columns present in table itself

Can you please suggest more on this ?

Regards
Tarkeshwar

Though the question still remains, what got it into that state?

Any recent hardware/software issues?
