DROPLANG(1)		PostgreSQL 9.6.19 Documentation		   DROPLANG(1)

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 32.14,
       "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
