I have a table in a partitioned structure, and the size of the table for the 10th month has doubled compared to previous months. On October 7, 2023, a failover was performed in this database, and the replica server became the master server. Before October 7th, this database was a replica, and after the failover, the auto vacuum parameter in the postgresql.conf file of the database remained commented out. I noticed this on November 11, 2023, and enabled the parameter. During this period, I believe the unchecked increase in table size was due to the auto vacuum parameter being turned off. What should I do to prevent this from affecting the 12th month and beyond?
