the command line.
- [-d, -dbname
- dbname ] Specifies from which database the language
should be removed.

droplang also accepts the following command line arguments for connection parameters:
- -h, -host host
- Specifies the hostname of the machine on which the postmaster
is running.
- -p, -port port

psql for more possibilities.
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.
Use createlang to add a language.
To remove pltcl:
$ droplang pltcl
