dropdb - Remove an existing Postgres database
SYNOPSIS
dropdb [ 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 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 postmas
ter is listening for connections.
-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 installation.
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 displayed. See DROP DATABASE [drop_database(l)]
and psql(1) for possibilities.
dropdb 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 interac
tive 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

underlying query:
