PROGRAM:

NAME


dropdb - remove a PostgreSQL database

SYNOPSIS


dropdb [connection-option...] [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:

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.

-V
--version
Print the dropdb version and exit.

--if-exists
Do not throw an error if the database does not exist. A notice is issued in this case.

-?
--help
Show help about dropdb command line arguments, and exit.

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
User name to connect as.

-w
--no-password
Never issue a password prompt. If the server requires password authentication and a
password is not available by other means such as a .pgpass file, the connection
attempt will fail. This option can be useful in batch jobs and scripts where no user
is present to enter a password.

-W
--password
Force dropdb to prompt for a password before connecting to a database.

This option is never essential, since dropdb will automatically prompt for a password
if the server demands password authentication. However, dropdb will waste a connection
attempt finding out that the server wants a password. In some cases it is worth typing
-W to avoid the extra connection attempt.

--maintenance-db=dbname
Specifies the name of the database to connect to in order to drop the target database.
If not specified, the postgres database will be used; if that does not exist (or is
the database being dropped), template1 will be used.

ENVIRONMENT


PGHOST
PGPORT
PGUSER
Default connection parameters

This utility, like most other PostgreSQL utilities, also uses the environment variables
supported by libpq (see Section 31.14, “Environment Variables”, in the documentation).

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

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.
Are you sure? (y/n) y
DROP DATABASE demo;
