because it's an OpenStreetMap Full planet database, which is huge (~ 2 TB), i don't have many backups. the last is from 20180608 ok, i can restore that and reload the incremential updates or reload full data starting from raw data. both will need some days. if i could get rid of the bad data-record, it's much easier to recover that. Running a vacuum or a vacuum full, is my last try.
