createlang [ connection options ] [ langname [ dbname
] ]

createlang accepts the following command line arguments:
- langname
- Specifies the name of the backend programming language to be
defined. createlang will prompt for langname if it is not specified on
the command line.
- -d, -dbname dbname
- Specifies which database the language should be
added.
- -l, -list
- Shows a list of already installed languages in the target database
(which must be specified).
createlang also accepts the following command line arguments for connection
parameters:
- -h, -host host
- Specifies the hostname of the machine on which the postmaster
is running.
- -p, -port port
- Specifies the Internet TCP/IP port or local Unix domain
socket file extension on which the postmaster is listening for connections.
- -U, -username username

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 for more possibilities.
createlang is a utility for adding a new programming language to a Postgres
database. createlang currently accepts two languages, plsql and pltcl.
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 for more.
Use droplang to remove a language.
To install pltcl:
$ createlang pltcl
