it depends on your cluster environment. you need to know how much wal is created in checkpoint_timeout duration. for example your
checkpoint_timeout = 30 min, you need to measure how much wal is created in 30 minute. and then you can increase max_wal_size according to this size.

how much size should I increase in "max_wal_size".
Do we need to change any other parameter's value also ?
