DROPDB(1) PostgreSQL Client Applications DROPDB(1)NAMEdropdb - remove a PostgreSQL database
SYNOPSISdropdb [ options... ] dbname
DESCRIPTIONdropdb 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 shell script wrapper around the SQL command
DROP DATABASE [drop_database(l)] via the PostgreSQL inter-
active 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.
OPTIONSdropdb accepts the following command-line arguments:
dbname Specifies the name of the database to be removed.
The database must be one of the existing PostgreSQL
databases in this installation.
-e
--echo Echo the queries 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.
createdb 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 host begins with a slash, it
is used as the directory for the Unix domain
socket.
-p port
--port port
Specifies the Internet TCP/IP 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
--password
Force password prompt.
