droplang -- remove a PostgreSQL procedural language
droplang [connection-option...] langname [dbname]
droplang [connection-option...] --list | -l dbname
droplang is a utility for removing an existing programming language from a PostgreSQL database. droplang can drop any procedural language, even those not supplied by the PostgreSQL distribution.
Although backend 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. See
droplang accepts the following command line arguments:
- Specifies the name of the backend programming language to be removed.
- Specifies from which database the language should be removed. The default is to use the database with the same name as the current system user.
- Display SQL commands as they are executed.
- Show a list of already installed languages in the target database.
droplang also accepts the following command line arguments for connection parameters:
- 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.
- Specifies the Internet TCP/IP port or local Unix domain socket file extension on which the server is listening for connections.
- User name to connect as
- Force password prompt.
- Default connection parameters
Most error messages are self-explanatory. If not, run
droplang with the
option and see under the respective SQL command
createlang to add a language.
To remove the language
$ droplang pltcl dbname
