Hi,
I ran load of 150GB JSON data on a table for 3 days and terminated the loading today.
When I ran manual Vacuum on the database, I found the below error on the toast table corresponding to the table on which I Loaded the data.
VACUUM(ANALYZE, VERBOSE)

Later, I thought the issue could be due to Transaction-Wraparound and did VACUUM(FREEZE, ANALYZE, VERBOSE). but that also throws same error

How do I get rid of this error? so that Vacuum gets complete?
Thanks,
