NAME
dropdb - remove a PostgreSQL database SYNOPSIS
dropdb [ options... ] dbname DESCRIPTION
dropdb destroys an existing PostgreSQL database. The user who executes this command must be a database superuser or the owner of the data- base. dropdb is a shell script wrapper around the SQL command DROP DATABASE [drop_database(7)] via the PostgreSQL interactive terminal psql(1). Thus, there is nothing special about dropping databases 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. OPTIONS
dropdb accepts the following command-line arguments: dbname Specifies the name of the database to be removed. The database must be one of the existing PostgreSQL databases in this installa- tion. -e --echo Echo the queries that dropdb generates and sends to the server. -i --interactive Issues a verification prompt before doing anything destructive. -q --quiet Do not display a response. createdb also accepts the following command-line arguments for connection parameters: -h host --host host Specifies the host name of the machine on which the server 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 -W --password Force password prompt. DIAGNOSTICS
DROP DATABASE The database was successfully removed. dropdb: Database removal failed. Something didn't work out. If there is an error condition, the backend error message will be displayed. See DROP DATABASE [drop_database(7)] and psql(1) for possi- bilities. ENVIRONMENT
PGHOST PGPORT PGUSER Default connection parameters EXAMPLES
To destroy the database demo on the default database server: $ dropdb demo DROP DATABASE To destroy the database demo using the server on host eden, port 5000, with verification and a peek at the underlying query: $ dropdb -p 5000 -h eden -i -e demo Database "demo" will be permanently deleted.

NAME
dropuser - remove a PostgreSQL user account SYNOPSIS
dropuser [ options... ] [ username ] DESCRIPTION
dropuser removes an existing PostgreSQL user and the databases which that user owned. Only users with usesuper set in the pg_shadow table can destroy PostgreSQL users. dropuser is a shell script wrapper around the SQL command DROP USER [drop_user(7)] via the PostgreSQL interactive terminal psql(1). 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. OPTIONS
dropuser accepts the following command-line arguments: username 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. -e --echo Echo the queries that dropuser generates and sends to the server. -i --interactive Prompt for confirmation before actually removing the user. -q --quiet 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 server 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) -W --password Force password prompt (to connect to the server, not for the password of the user to be dropped). ENVIRONMENT
PGHOST PGPORT PGUSER Default connection parameters DIAGNOSTICS
DROP USER All is well. dropuser: deletion of user "username" failed Something went wrong. The user was not removed. If there is an error condition, the backend error message will be displayed. See DROP USER [drop_user(7)] and psql(1) for possibilities. EXAMPLES
To remove user joe from the default database server: $ dropuser joe DROP USER To remove user joe using the postmaster on host eden, port 5000, with verification and a peek at the underlying query: $ dropuser -p 5000 -h eden -i -e joe User "joe" and any owned databases will be permanently deleted. Are you sure? (y/n) y DROP USER "joe" DROP USER SEE ALSO
