Users/Roles do not align.

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/12/ddl-schemas.html
Description:

According to Section 5.9. Schemas:
https://www.postgresql.org/docs/12/ddl-schemas.html
`A PostgreSQL database cluster contains one or more named databases. Users
and groups of users are shared across the entire cluster, but no other data
is shared across databases. Any given client connection to the server can
access only the data in a single database, the one specified in the
connection request.`

According to Chapter 21. Database Roles:
https://www.postgresql.org/docs/12/user-manag.html
`In PostgreSQL versions before 8.1, users and groups were distinct kinds of
entities, but now there are only roles. Any role can act as a user, a group,
or both.`

Based on this, I believe Section 5.9 should read:
`A PostgreSQL database cluster contains one or more named databases. Roles
are shared across the entire cluster, but no other data is shared across
databases. Any given client connection to the server can access only the
data in a single database, the one specified in the connection request.`
