dropdb - Unix, Linux Command
NAME
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_database(7)].
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:
Tag | Description |
dbname

|
-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
|

|
|
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
extension on which the server
is listening for connections.
|
-U username
--username username

DIAGNOSTICS
In case of difficulty, see DROP DATABASE [drop_database(7)] and psql(1) for
discussions of potential problems and error messages.
The database server must be running at the
targeted host. Also, any default connection 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.
