DROP ROLE¶
Function¶
DROP ROLE deletes a specified role.
Precautions¶
If a "role is being used by other users" error is displayed when you run DROP ROLE, it might be that threads cannot respond to signals in a timely manner during the CLEAN CONNECTION process. As a result, connections are not completely cleared. In this case, you need to run CLEAN CONNECTION again.
Syntax¶
DROP ROLE [ IF EXISTS ] role_name [, ...];
Parameter Description¶
IF EXISTS
Sends a notice instead of an error if the specified role does not exist.
role_name
Specifies the name of the role to be deleted.
Value range: An existing role.
Examples¶
Delete the manager role.
DROP ROLE manager;
