Re: "Required checkpoints occurs too frequently"

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.
