Removes a database.
dropdb [connection-option ...] [-e] [-i] dbname dropdb -? | --help dropdb -V | --version
dropdb destroys an existing database. The user who executes this command must be a superuser or the owner of the database being dropped.
dropdb is a wrapper around the SQL command DROP DATABASE. See the Greenplum Database Reference Guide for information about DROP DATABASE.
- 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.
- 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.
- -h host | --host=host
- The host name of the machine on which the Greenplum master database server is running. If not specified, reads from the environment variable PGHOST or defaults to localhost.
- -p port | --port=port
- The TCP port on which the Greenplum master database server is listening for connections. If not specified, reads from the environment variable PGPORT or defaults to 5432.
- -U username | --username=username
- The database role name to connect as. If not specified, reads from the environment variable PGUSER or defaults to the current system role name.
- -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 a password prompt.
- 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 if it is the name of the database being dropped), template1 will be used.
