The last minor release in the 9.3 branch was 9.3.25. More to the point, the 9.3 branch has been out of support for nearly 3 years. You are upgrading your OS because it is out of support; you need to do the same for your database. I concur with David's nearby suggestion that the PG v12 branch might be a suitable migration target for you. 12.7 is current, although 12.8 is due out next week. regards, tom lane
