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
