pg_dump: SQL command 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.i...... TO stdout;
pg_dumpall: pg_dump failed on database "aaaa", exiting

I tried to do pg_dumpall on a read-only hotstandby. This error??
Time taken to dump longer than archive_timeout is the problem?
