Yeah, SELECT FOR UPDATE should overwrite the broken xmax value and thereby fix it, I expect. However, I don't see anything in the release notes suggesting that we've fixed any related bugs since 9.6.10, so if this just appeared then we've still got a problem :-(. Did anything interesting happen since your last successful autovacuum on that table? Database crashes, WAL-related parameter changes, that sort of thing? regards, tom lane
