Issue in tablebackup

[srini ram <seenuram777@xxxxxxxxx>]

Hi Experts,

I am facing below error while taking a table back.

producation_db=# select * into tblconfmresult27072020 from tblconfmresult;
ERROR:  missing chunk number 0 for toast value 4543659 in pg_toast_24175
producation_db =#

kindly assist me in taking the backup of this error table from my production database.

I tried table vacuum and re-index of this issue table but still, it was not helping to resolve this issue.

Thanks&Regards,
