The OP did that:
...
alter user backup_admin set role to dba_admin;
When I followed their steps I got:
aklaver@tito:~> psql -d test -U backup_admin
Null display is "NULL".
psql (9.6.2)
Type "help" for help.
test=# select session_user, current_user;
session_user | current_user
--------------+--------------
backup_admin | dba_admin
(1 row)
test=# \drds
List of settings
Role | Database | Settings
--------------+----------+----------------
backup_admin | | role=dba_admin
aklaver@tito:~> pg_basebackup -p 5432 -h 127.0.0.1 -U backup_admin -D
pg_test/
Password:
pg_basebackup: could not connect to server: FATAL: must be superuser or
replication role to start walsender
So I would also be interested in knowing why it does not work?
