PostgreSQL – Drop User
To delete or drop a user from PostgreSQL, run DROP USER command. The syntax is as shown below.
DROP USER [ IF EXISTS ] username [, ...]where username is the name of the user you would like to drop from PostgreSQL.
IF EXISTS which is optional checks if the user is available and then proceeds with the action.

In this example, we are going to drop user lini. To delete the user, we run the following command.
DROP USER IF EXISTS lini;
The user is successfully deleted from PostgreSQL database.
Example 2 – Delete multiple Users

DROP USER IF EXISTS lini, kiku, jobin;
The user is successfully deleted from PostgreSQL database.
