Let's say I expect to have a billion users in my Postgres users table.
I want to make sure the first user gets to set it's role attribute to enum :admin as the default when the record is created and all other users are enum :user.
Of course a billion users is ridiculous. I'm just trying to understand what the, uh, best way to see if a Postgres table is empty without actually having to load it.
