DESCRIPTION

droplang is a utility for removing an existing programming language from a PostgreSQL database. droplang can drop any procedural language, even those not supplied by the PostgreSQL distribution.

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 [__drop_language__(l)? for more.

NOTES

Use createlang(1) to add a language.

USAGE

To remove pltcl:

$ droplang pltcl dbname
