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 Post-
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 eas-
ier to use. See DROP LANGUAGE [drop_language(7)] for more.
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.
--echo Display SQL commands as they are executed.
--list 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.
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.
Force droplang to prompt for a password before connecting to a database.
This option is never essential, since droplang will automatically prompt for a
password if the server demands password authentication. However, droplang 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.
PGUSER Default connection parameters
This utility, like most other PostgreSQL utilities, also uses the environment variables
supported by libpq (see in the documentation).
Most error messages are self-explanatory. If not, run droplang with the --echo option and
see under the respective SQL command for details. Also, any default connection settings
and environment variables used by the libpq front-end library will apply.
Use createlang(1) to add a language.
To remove the language pltcl:
$ droplang pltcl dbname
createlang(1), DROP LANGUAGE [drop_language(7)]
