all it workers stoped with this messages:
ERROR: found xmin 982973690 from before relfrozenxid 2702858737
CONTEXT: automatic vacuum of table "avito_delta.pg_catalog.pg_authid"
ERROR: found xmin 982973690 from before relfrozenxid 2702858761
CONTEXT: automatic vacuum of table "avito_delta.pg_catalog.pg_auth_members"
