dropdb destroys an existing
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
DROP DATABASE via
the PostgreSQL interactive terminal
psql. 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.
dropdb accepts the following command-line arguments:
Specifies the name of the database to be removed. The database
must be one of the existing PostgreSQL databases
in this installation.
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:
-h host --host host
Specifies the host name of the machine on which the
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
Force password prompt.
The database was successfully removed.

If there is an error condition, the backend error message will be displayed.
