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 shell script wrapper around the
SQL command
via
the PostgreSQL interactive terminal
. 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.
Options
-h, --host host
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.
-p, --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
User name to connect as
-W, --password
Force password prompt.
-e, --echo
Echo the queries that dropdb generates
and sends to the server.
-q, --quiet
Do not display a response.
-i, --interactive
Issues a verification prompt before doing anything destructive.
dbname
Specifies the name of the database to be removed. The database
must be one of the existing PostgreSQL databases
in this installation.
The options -h, -p, -U,
-W, and -e are passed on literally to
.
