The link that I posted appears to be useless without modification. Use this instead. https://commitfest.postgresql.org/17/1542/ It feels related to my problem, even though I'm not using tablespaces.

Hi!I experience that it takes a long time (several GB of data is fetched) to use pg_rewind to do a failback when the former master has failed over to the former standby (which is now master) and is started again and very little data (like one row updated) is updated. I have upgraded to the latest version (10.5), but still think it takes equally long time. I found this bugfix (https://www.postgresql.org/message-id/flat/0A3221C70F24FB45833433255569204D1F8D6C7A@G01JPEXMBYT05) from late February this year. So would like to check if somebody knows if this fix is incorporated in standard postgreSQL, or if anybody else experience the same issue.Thanks for any answer!/Regards Joakim Lundgren
