I am using a new PostgreSQL 12 installation on a Linux box and would like
to be able to back up the entire cluster as an ordinary user.
I already have myself set up as an ordinary pg user with the same name as
my Linux name, and I am using a .pgpass file for easy access.
I know I can, inside Postgres, grant myself select access on an
object-by-object basis, but is there any simpler way to do it for the whole
cluster?
Thanks.
