## Description

droplang is a utility for removing an existing programming language from a Postgres database. droplang currently accepts two languages, `plsql` and `pltcl`.

Although backend programming languages can be removed directly using several SQL commands, it is recommended to use droplang because it performs a number of checks and is much easier to use. See DROP LANGUAGE for more.

## Notes

Use createlang to add a language.

## Usage

To remove `pltcl`:

    $ droplang pltcl
