dropuser removes an existing
and the databases which that user owned.
Only users with usesuper set in
the pg_shadow table can destroy
dropuser is a shell script wrapper around the
DROP USER via
the PostgreSQL interactive terminal
psql. Thus, there is nothing
special about removing users via this or other methods. This means
that the psql must be found by the script and that
a database server is running at the targeted host. Also, any default
settings and environment variables available to psql
and the libpq front-end library do apply.
dropuser accepts the following command-line arguments:
Specifies the name of the PostgreSQL user to be removed.
This name must exist in the PostgreSQL installation.
You will be prompted for a name if none is specified on the command line.
Echo the queries 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:
-h host --host host
Specifies the host name of the machine on which the
is running. If host begins with a slash, it is used
as the directory for the Unix domain socket.
-p port --port port
Specifies the Internet TCP/IP port or local Unix domain socket file
extension on which the server
is listening for connections.
-U username --username username
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).
PGHOST PGPORT PGUSER
Default connection parameters
All is well.
