createlang

CREATELANG(1)						  PostgreSQL Client Applications					     CREATELANG(1)

NAME

       createlang - define a new PostgreSQL procedural language

SYNOPSIS

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

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

DESCRIPTION

       createlang  is  a utility for adding a new programming language to a PostgreSQL database.  createlang can handle all the languages supplied
       in the default PostgreSQL distribution, but not languages provided by other parties.

       Although backend programming languages can be added directly using several SQL commands, it is recommended to  use  createlang  because	it
       performs a number of checks and is much easier to use. See CREATE LANGUAGE [create_language(7)] for additional information.

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 sys-
	      tem user.

       -e

       --echo Displays SQL commands as they are executed.

       -l

       --list Shows a list of already installed languages in the target database (which must be specified).

       -L directory
	      Specifies the directory in which the language interpreter is to be found. The directory is normally found automatically; this option
	      is primarily for debugging purposes.

       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 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

       --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. Check also under psql(1) for more possibilities.

NOTES

       Use droplang(1) to remove a language.

       createlang is a shell script that invokes psql several times. If you have things arranged so that a password prompt is required to connect,
       you will be prompted for a password several times.

EXAMPLES

       To install pltcl into the database template1:

       $ createlang pltcl template1
