doc: Update description of rolreplication column

Browse Source 
Since PostgreSQL 9.6, rolreplication no longer determines whether a role
can run pg_start_backup() and pg_stop_backup(), so remove that.

Add that this attribute determines whether a role can create and drop
replication slots.

These clauses determine whether a role is allowed to initiate
streaming replication or put the system in and out of backup mode.
These clauses determine whether a role is a replication role. A role
must have this attribute (or be a superuser) in order to be able to
connect to the server in replication mode (physical or logical
replication) and in order to be able to create or drop replication
slots.
A role having the <literal>REPLICATION</> attribute is a very
highly privileged role, and should only be used on roles actually
used for replication. If not specified,
