Description

droplang removes an existing programming language from a database. droplang can drop any procedural language, even those not supplied by the Greenplum Database distribution.

Although programming languages can be removed directly using several SQL commands, it is recommended to use droplang because it performs a number of checks and is much easier to use.

droplang is a wrapper for the SQL command DROP LANGUAGE.

Options

langname
Specifies the name of the programming language to be removed.
[-d] dbname | [--dbname] dbname
Specifies from which database the language should be removed. The default is to use the PGDATABASE environment variable setting, or the same name as the current system user.
-e | --echo
Echo the commands that droplang generates and sends to the server.
-l | --list
Show a list of already installed languages in the target database.

Connection Options

-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.

Examples

To remove the language pltcl from the mydatabase database:
