Creating, altering, and deleting users
Database users are global across a data warehouse cluster (and not for each individual database).
-
To create a user, use the CREATE USER command.
-
To create a superuser, use the CREATE USER command with the CREATEUSER option.
-
To remove an existing user, use the DROP USER command.
-
To change a user, for example changing a password, use the ALTER USER command.
-
To view a list of users, query the PG_USER catalog table.
select * from pg_user; usename | usesysid | usecreatedb | usesuper | usecatupd | passwd | valuntil | useconfig ------------+----------+-------------+----------+-----------+----------+----------+----------- rdsdb | 1 | t | t | t | ******** | | masteruser | 100 | t | t | f | ******** | | dwuser | 101 | f | f | f | ******** | | simpleuser | 102 | f | f | f | ******** | | poweruser | 103 | f | t | f | ******** | | dbuser | 104 | t | f | f | ******** | | (6 rows)
