SYNOPSISdropdb [ options... ] dbname
INPUTS
-h, --host host
Specifies the hostname of the machine on which the postmaster is
running. If host begins with a slash, it is used as the direc‐
tory for the unix domain socket.
-p, --port port
Specifies the Internet TCP/IP port or local Unix domain socket
file extension on which the postmaster is listening for connec‐
tions.
-U, --username username
Username to connect as.
-W, --password
Force password prompt.
-e, --echo
Echo the queries that dropdb generates and sends to the backend.
-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 Postgres databases in this installa‐
tion.
The options -h, -p, -U, -W, and -e are passed on literally to psql(1).
OUTPUTS
DROP DATABASE
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 dis‐
played. See DROP DATABASE [drop_database(l)] and psql(1) for possibil‐
ities.
DESCRIPTIONdropdb destroys an existing Postgres 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(l)] via the Postgres 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 apply.
USAGE
To destroy the database demo on the default database server:
$ dropdb demo
DROP DATABASE
To destroy the database demo using the postmaster on host eden, port
5000, with verification and a peek at the underlying query:
$ dropdb-p 5000 -h eden -i -e demo
Database "demo" will be permanently deleted.
Are you sure? (y/n) y
