Description:

Hello,

We use Postgresql -15. We need a account and the account should read all
data. We previgles this group permission . (read_all_data)

When I add this group privigles, the account have pg_dump permission. Why?
How do I prevent this?.

There is no pg_dump permission. But an account that can read all data is
certainly capable of exercising that right via the pg_dump utility, or any
other client for that matter.
