NAME dropdb - remove a PostgreSQL database
SYNOPSIS dropdb [ option... ] dbname
DESCRIPTION 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 [drop_database(7)]. There is no effective difference between dropping databases via this utility and via other methods for accessing the server.
OPTIONS dropdb accepts the following command-line arguments:
dbname Specifies the name of the database to be removed.
--echo Echo the commands that dropdb generates and sends to the server.
--interactive Issues a verification prompt before doing anything destructive.
--quiet Do not display a response.
dropdb also accepts the following command-line arguments for connection parameters:
--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.
--port port Specifies the TCP port or local Unix domain socket file exten- sion on which the server is listening for connections.
--username username User name to connect as
--password Force password prompt.
PGUSER Default connection parameters
DIAGNOSTICS In case of difficulty, see DROP DATABASE [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 connec- tion settings and environment variables used by the libpq front-end library will apply.
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 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
