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 [drop_language(l)]
for more.
NOTES
Use createlang(1) to add a language.
USAGE
To remove pltcl:
$ droplang pltcl
