SYNOPSISdropuser [ option... ] [ username ]
DESCRIPTIONdropuser removes an existing PostgreSQL user. Only superusers and
users with the CREATEROLE privilege can remove PostgreSQL users. (To
remove a superuser, you must yourself be a superuser.)

ity and via other methods for accessing the server.

--echo Echo the commands that dropuser generates and sends to the
Prompt for confirmation before actually removing the user.

User name to connect as (not the user name to drop)
Force password prompt (to connect to the server, not for the
password of the user to be dropped).

In case of difficulty, see DROP ROLE [drop_role(7)] and psql(1) for

tion settings and environment variables used by the libpq front-end
library will apply.
