       createlang - install a PostgreSQL procedural language

       createlang [connection-option...] langname [dbname]

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

       createlang is a utility for adding a procedural language to a
       PostgreSQL database.

       createlang is just a wrapper around the CREATE EXTENSION
       (CREATE_EXTENSION(7)) SQL command.

	   createlang is deprecated and may be removed in a future PostgreSQL
	   release. Direct use of the CREATE EXTENSION command is recommended

       createlang accepts the following command-line arguments:

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

       [-d] dbname, [--dbname=]dbname
	   Specifies the database to which the language should be added. 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 createlang version and exit.

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

       createlang 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 the value begins with a slash, it is used as the
	   directory for the Unix domain socket.

       -p port, --port=port
	   Specifies the TCP 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 createlang to prompt for a password before connecting to a

	   This option is never essential, since createlang will automatically
	   prompt for a password if the server demands password
	   authentication. However, createlang 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.

	   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).

       Most error messages are self-explanatory. If not, run createlang with
       the --echo option and see the respective SQL command for details. Also,
       any default connection settings and environment variables used by the
       libpq front-end library will apply.

       Use droplang(1) to remove a language.

       To install the language pltcl into the database template1:

	   $ createlang pltcl template1

       Note that installing the language into template1 will cause it to be
       automatically installed into subsequently-created databases as well.
