Name

dropdb — remove a PostgreSQL™ database

Synopsis

dropdb [connection-option...] [option...] dbname

Options

dropdb accepts the following command-line arguments:

dbname

Specifies the name of the database to be removed.

-e, --echo

Echo the commands that dropdb generates and sends to the server.

-i, --interactive

Issues a verification prompt before doing anything destructive.

-V, --version

Print the dropdb version and exit.

--if-exists

Do not throw an error if the database does not exist. A notice is issued in this case.

-?, --help

Show help about dropdb command line arguments, and exit.

dropdb 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 the value begins with a slash, it is used as the directory for the Unix domain socket.

-p port, --port=port

Specifies the TCP 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, --no-password

Never issue a password prompt. If the server requires password authentication and a password is not available by other means such as a .pgpass file, the connection attempt will fail. This option can be useful in batch jobs and scripts where no user is present to enter a password.

-W, --password

Force dropdb to prompt for a password before connecting to a database.

This option is never essential, since dropdb will automatically prompt for a password if the server demands password authentication. However, dropdb will waste a connection attempt finding out that the server wants a password. In some cases it is worth typing -W to avoid the extra connection attempt.

--maintenance-db=dbname

Specifies the name of the database to connect to in order to drop the target database. If not specified, the postgres database will be used; if that does not exist (or is the database being dropped), template1 will be used.

Diagnostics

In case of difficulty, see DROP DATABASE(7) and psql(1) for discussions of potential problems and error messages. The database server must be running at the targeted host. Also, any default connection settings and environment variables used by the libpq front-end library will apply.
