dropdb - remove a PostgreSQL database
dropdb [ options... ] dbname
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 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
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 installation.
--echo Echo the queries that dropdb generates and sends to the server.
Issues a verification prompt before doing anything destructive.
Do not display a response.
createdb also accepts the following command-line arguments for connection parameters:
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.
Specifies the Internet TCP/IP port or local Unix domain socket file extension on
which the server is listening for connections.
User name to connect as
Force password prompt.
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 possibilities.
