- Adds or removes a user (role) from a PostgreSQL server instance
|
||||
- Creates, alters, or removes a user (role) from a PostgreSQL server instance
|
||||
("cluster" in PostgreSQL terminology) and, optionally,
|
||||
grants the user access to an existing database or tables.
|
||||
- A user is a role with login privilege.
|
||||
- The fundamental function of the module is to create, or delete, users from
|
||||
a PostgreSQL instances. Privilege assignment, or removal, is an optional
|
||||
step, which works on one database at a time. This allows for the module to
|
||||
be called several times in the same module to modify the permissions on
|
||||
different databases, or to grant permissions to already existing users.
|
||||
- A user cannot be removed until all the privileges have been stripped from
|
||||
the user. In such situation, if the module tries to remove the user it
|
||||
will fail. To avoid this from happening the fail_on_user option signals
|
||||
the module to try to remove the user, but if not possible keep going; the
|
||||
module will report if changes happened and separately if the user was
|
||||
removed or not.
|
||||
- You can also use it to grant or revoke user's privileges in a particular database.
|
||||
- You cannot remove a user while it still has any privileges granted to it in any database.
|
||||
- Set I(fail_on_user) to C(no) to make the module ignore failures when trying to remove a user.
|
||||
In this case, the module reports if changes happened as usual and separately reports
|
||||
whether the user has been removed or not.
