Hi All: The autovacuum (prevent wraparound) still run more than 36 hours, I can not drop the partition table after adjust the autovacuum parameters. If a table is running autovacuum (prevent wraparound), can I purge this table? If not, what else I can do for clean this partition table? If the table is running autovacuum (prevent wraparound), can I use pg_dump to backup it? Will the Transaction ID Wraparound Failures happen while table has been restored into new DB?
