DROPLANG(1)			  PostgreSQL 9.2.7 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 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
