DROP ROLE(7)                                              SQL Commands                                              DROP ROLE(7)



NAME
       DROP ROLE - remove a database role


SYNOPSIS
       DROP ROLE [ IF EXISTS ] name [, ...]


DESCRIPTION
       DROP  ROLE  removes the specified role(s).  To drop a superuser role, you must be a superuser yourself; to drop non-supe-
       ruser roles, you must have CREATEROLE privilege.

       A role cannot be removed if it is still referenced in any database of the cluster; an error will be raised if so.  Before
       dropping the role, you must drop all the objects it owns (or reassign their ownership) and revoke any privileges the role
       has been granted. The REASSIGN OWNED [reassign_owned(7)] and DROP OWNED [drop_owned(7)] commands can be useful  for  this
       purpose.

       However,  it  is not necessary to remove role memberships involving the role; DROP ROLE automatically revokes any member-
       ships of the target role in other roles, and of other roles in the target role.  The other roles are not dropped nor oth-
       erwise affected.

PARAMETERS
       IF EXISTS
              Do not throw an error if the role does not exist. A notice is issued in this case.

       name   The name of the role to remove.

NOTES
       PostgreSQL  includes  a program dropuser [dropuser(1)] that has the same functionality as this command (in fact, it calls
       this command) but can be run from the command shell.

EXAMPLES
       To drop a role:

       DROP ROLE jonathan;


COMPATIBILITY
       The SQL standard defines DROP ROLE, but it allows only one role to be dropped at a time, and it specifies different priv-
       ilege requirements than PostgreSQL uses.
