dropdb destroys an existing PostgreSQL database. The user who executes this command must be a database superuser or the owner of the database.
dropdb is a wrapper around the SQL command DROP DATABASE. There is no effective difference between dropping databases via this utility and via other methods for accessing the server.
dropdb accepts the following command-line arguments:
Specifies the name of the database to be removed.
Echo the commands that dropdb generates and sends to the server.
Issues a verification prompt before doing anything destructive.
Do not display a response.
dropdb 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
Force password prompt.
In case of difficulty, see DROP DATABASE and psql 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.
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 command:
$ dropdb -p 5000 -h eden -i -e demo Database "demo" will be permanently deleted. Are you sure? (y/n) y DROP DATABASE "demo" DROP DATABASE
