dropdb - remove a PostgreSQL database
SYNOPSIS
dropdb [ option... ] dbname
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 wrapper around the SQL command DROP DATABASE [drop_data‐
base(5)]. There is no effective difference between dropping databases
via this utility and via other methods for accessing the server.
OPTIONS
dropdb accepts the following command-line arguments:
dbname Specifies the name of the database to be removed.
-e
--echo Echo the commands that dropdb generates and sends to the server.
-i
--interactive
Issues a verification prompt before doing anything destructive.
-q
--quiet
Do not display a response.
dropdb also accepts the following command-line arguments for connection
parameters:
-h host
--host host
Specifies the host name of the machine on which the server is
running. If the value begins with a slash, it is used as the
directory for the Unix domain socket.
-p port
--port port
Specifies the TCP port or local Unix domain socket file exten‐
sion on which the server is listening for connections.
-U username
--username username
User name to connect as
-W
--password
Force password prompt.
ENVIRONMENT
PGHOST
PGPORT
PGUSER Default connection parameters
DIAGNOSTICS
In case of difficulty, see DROP DATABASE [drop_database(5)] and psql(1)
for discussions of potential problems and error messages. The database
server must be running at the targeted host. Also, any default connec‐
tion settings and environment variables used by the libpq front-end
library will apply.
EXAMPLES
To destroy the database demo on the default database server:
$ dropdb demo
DROP DATABASE
To destroy the database demo using the server on host eden, port 5000,
with verification and a peek at the underlying command:
$ dropdb -p 5000 -h eden -i -e demo
Database "demo" will be permanently deleted.
