Description
createlang is a utility for adding a new programming language to a Postgres database. createlang currently accepts several languages, plpgsql, pltcl, pltclu, and plperl.
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.
