-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:

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
for more.
Notes
Use 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.
