NAME
       createlang - define a new PostgreSQL procedural language


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

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

DESCRIPTION
       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, which see for additional infor-
       mation.

OPTIONS
       createlang accepts the following command-line arguments:

       langname
	      Specifies the name of the procedural programming language to  be
	      defined.

       [-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.

       -e

       --echo Display SQL commands as they are executed.

       -l

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


       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.

       -W

       --password
	      Force password prompt.


ENVIRONMENT
       PGDATABASE

       PGHOST

       PGPORT

       PGUSER Default connection parameters

DIAGNOSTICS
       Most error messages are self-explanatory. If not, run  createlang  with
       the --echo option and see under the respective SQL command for details.

NOTES
       Use droplang(1) to remove a language.

EXAMPLES
       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.
