I hope this email finds you well. I would like to apologize in advance for any language mistakes, as my English is not very good. However, I will do my best to communicate clearly.
Regarding the report "BUG #18773: オートバキュームのリトライ時にreltuplesの値が減少する" submitted from the email address "antengynnnn536(at)gmail(dot)com", I am writing to inform you that I work at the same company. Since the owner of the mentioned email address is away from work for a while, I will be corresponding on their behalf.
I have already contacted AWS Support for verification regarding this issue. Although the case was escalated to their development department, AWS stated that this behavior is due to a PostgreSQL specification and they would not address it. They recommended contacting PostgreSQL directly.
In our company's environment, we rely heavily on Autovacuum and Autoanalyze for database management due to the high load of executing many SQL queries and managing execution plans. If Autovacuum causes the reltuples value to become inaccurate, it could significantly impact SQL performance, resulting in substantial influence.
Since this issue could also cause unintended SQL delays for other users, we are hoping for an improvement in this area.
Thank you very much for your attention to this matter.
Best regards,
