       createlang - define a new PostgreSQL procedural language

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

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

       createlang  is  a  utility  for	adding a new programming language to a
       PostgreSQL database.  createlang is just a wrapper  around  the	CREATE
       LANGUAGE [create_language(7)] command.

       createlang accepts the following command-line arguments:

	      Specifies	 the name of the procedural programming language to be

       [-d] dbname

       [--dbname] dbname
	      Specifies to which database the language should be  added.   The
	      default is to use the database with the same name as the current
	      system user.


       --echo Display SQL commands as they are executed.


       --list Show a list of already installed languages in the	 target	 data‐

       createlang  also	 accepts the following command-line arguments for con‐
       nection 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	exten‐
	      sion on which the server is listening for connections.

       -U username

       --username username
	      User name to connect as.


	      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.


	      Force createlang to prompt for a password before connecting to a

	      This option is never essential, since createlang will  automati‐
	      cally  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




       PGUSER Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the envi‐
       ronment variables supported by libpq (see in the documentation).

       Most error messages are self-explanatory. If not, run  createlang  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.

       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.
