NAME
       droplang - remove a PostgreSQL procedural language

SYNOPSIS
       droplang [connection-option...] langname [dbname]

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

DESCRIPTION
       droplang is a utility for removing an existing procedural language from
       a PostgreSQL database.

       droplang is just a wrapper around the DROP EXTENSION
       (DROP_EXTENSION(7)) SQL command.

	   Caution
	   droplang is deprecated and may be removed in a future PostgreSQL
	   release. Direct use of the DROP EXTENSION command is recommended
	   instead.

OPTIONS
       droplang accepts the following command line arguments:

       langname
	   Specifies the name of the procedural language to be removed. (This
	   name is lower-cased.)

       [-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
	   Display SQL commands as they are executed.

       -l, --list
	   Show a list of already installed languages in the target database.

       -V, --version
	   Print the droplang version and exit.

       -?, --help
	   Show help about droplang command line arguments, and exit.

       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, --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 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.

ENVIRONMENT
       PGDATABASE, PGHOST, PGPORT, PGUSER
	   Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the
       environment variables supported by libpq (see Section 31.14,
       "Environment Variables", in the documentation).

DIAGNOSTICS
       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.

NOTES
       Use createlang(1) to add a language.

EXAMPLES
       To remove the language pltcl:

	   $ droplang pltcl dbname
