#SQL TABS POSTGRESQL SUPERUSER PASSWORD#
Specify a password upon role creation with CREATE ROLE name PASSWORD ' string'.Ī role's attributes can be modified after creation with ALTER ROLE. Database passwords are separate from operating system passwords. The password and md5 authentication methods make use of passwords. passwordĪ password is only significant if the client authentication method requires the user to supply a password when connecting to the database. To create such a role, use CREATE ROLE name REPLICATION LOGIN. A role used for streaming replication must have LOGIN permission as well. initiating replicationĪ role must explicitly be given permission to initiate streaming replication (except for superusers, since those bypass all permission checks). However, to create, alter, drop, or change membership of a superuser role, superuser status is required CREATEROLE is insufficient for that. A role with CREATEROLE privilege can alter and drop other roles, too, as well as grant or revoke membership in them. To create such a role, use CREATE ROLE name CREATEROLE. role creationĪ role must be explicitly given permission to create more roles (except for superusers, since those bypass all permission checks). To create such a role, use CREATE ROLE name CREATEDB. database creationĪ role must be explicitly given permission to create databases (except for superusers, since those bypass all permission checks). You must do this as a role that is already a superuser.
To create a new database superuser, use CREATE ROLE name SUPERUSER. This is a dangerous privilege and should not be used carelessly it is best to do most of your work as a role that is not a superuser. ( CREATE USER is equivalent to CREATE ROLE except that CREATE USER assumes LOGIN by default, while CREATE ROLE does not.) superuser statusĪ database superuser bypasses all permission checks, except the right to log in. To create a role with login privilege, use either: CREATE ROLE name LOGIN A role with the LOGIN attribute can be considered the same as a “ database user”. Only roles that have the LOGIN attribute can be used as the initial role name for a database connection.
