DROPLANG(1)						  PostgreSQL Client Applications					       DROPLANG(1)

NAME

       droplang - remove a PostgreSQL procedural language

SYNOPSIS

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

       droplang [ connection-options... ]  --list | -l dbname

DESCRIPTION

       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 DROP LANGUAGE [drop_language(7)] for more.

OPTIONS

       droplang accepts the following command line arguments:

       langname
	      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.

       -e

       --echo Displays SQL commands as they are executed.

       -l

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

       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

       -W

       --password
	      Force password prompt.

ENVIRONMENT

       PGDATABASE

       PGHOST

       PGPORT

       PGUSER Default connection parameters.

DIAGNOSTICS

       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 possibilities.

NOTES

       Use createlang(1) to add a language.

EXAMPLES

       To remove pltcl:

       $ droplang pltcl dbname
