dropuser1Applicationdropuserremove a PostgreSQL user accountdropuseroptionusernameDescriptiondropuser removes an existing
PostgreSQL user
and the databases which that user owned.
Only superusers (users with usesuper set in
the pg_shadow table) can destroy
PostgreSQL users.
dropuser is a wrapper around the
SQL command . The database server must be running
on the targeted host. There is nothing special about removing
users via this or other methods. Also, any default settings and
environment variables used by the libpq
front-end library will apply.
Optionsdropuser accepts the following command-line arguments:
username
Specifies the name of the PostgreSQL user to be removed.
You will be prompted for a name if none is specified on the command line.
Echo the commands that dropuser generates
and sends to the server.
Prompt for confirmation before actually removing the user.
Do not display a response.
createuser also accepts the following
command-line arguments for connection parameters:
Specifies the host name of the machine on which the
server
is running. If the value begins with a slash, it is used
as the directory for the Unix domain socket.
Specifies the TCP port or local Unix domain socket file
extension on which the server
is listening for connections.
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).
