       droplang - remove a PostgreSQL procedural language

       droplang [ connection-options... ] langname [ dbname ]

       droplang [ connection-options... ]  --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-
       greSQL 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  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.

       [-d] dbname

       [--dbname] dbname
	      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 Displays SQL commands as they are executed.


       --list Shows a list of already installed languages in the target database (which  must  be

       droplang 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


	      Force password prompt.




       PGUSER Default connection parameters.

       Most  error messages are self-explanatory. If not, run droplang with the --echo option and
       see under the respective SQL command for details. Check also under psql(1) for more possi-

       Use createlang(1) to add a language.

       To remove pltcl:

       $ droplang pltcl dbname

       createlang(1), DROP LANGUAGE [drop_language(7)]
