Re: [BUGS] pg_dump's results have quite different size

Yes. The pg_dump quits with the message:

pg_dump: Dumping the contents of table "data_histories" failed: PQgetResult() failed.

pg_dump: Error message from server: ERROR:  canceling statement due to conflict with recovery

DETAIL:  User query might have needed to see row versions that must be removed.

pg_dump: The command was: COPY public.data_histories (id, user_id, user_name, type, type_id, old_data, action, new_data, created_at, updated_at) TO stdout;
