CREATELANG(1) PostgreSQL Client Applications CREATELANG(1)
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 can handle all the languages supplied
in(1,8) the default PostgreSQL distribution, but not languages provided by
other parties.
Although backend programming languages can be added directly using sev-
eral SQL commands, it is recommended to use createlang because it per-
forms 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
system user.
-e
--echo Display SQL commands as they are executed.
-l
--list Show a list of already installed languages in(1,8) the target data-
base.
-L directory
Specifies the directory in(1,8) 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 con-
nection parameters:
-h host(1,5)
--host host(1,5)
Specifies the host(1,5) 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(2,7,n) file(1,n) 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

DIAGNOSTICS
Most error(8,n) 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:
