DROPLANG(1)
NAME
  droplang - remove a PostgreSQL procedural language

SYNOPSIS
  droplang [ connection-option... ]  langname [ dbname ]

  droplang [ connection-option... ]   [ --list ]  [ -l ]  dbname

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(5)] for more.

OPTIONS
  droplang accepts the following command line arguments:

  langname
       Specifies the name of the backend programming language to be removed.

  [-d] dbname

  [--dbname] dbname
       Specifies from which database the language should be removed.  The
       default is to use the database with the same name as the current
       system user.

  -e

  --echo
       Display SQL commands as they are executed.

  -l

  --list
       Show a list of already installed languages in the target database.

  droplang also accepts the following command line arguments for connection
  parameters:

  -h host

  --host host
       Specifies the host name of the machine on which the server is running.
       If host begins with a slash, it is used as the directory for the Unix
       domain socket.

  -p port

  --port port
       Specifies the Internet TCP/IP port or local Unix domain socket file
       extension on which the server is listening for connections.

  -U username

  --username username
       User name to connect as

  -W

  --password
       Force password prompt.

ENVIRONMENT
  PGDATABASE

  PGHOST

  PGPORT

  PGUSER
       Default connection parameters

  This utility, like most other PostgreSQL utilities, also uses the
  environment variables supported by libpq (see in the documentation).

DIAGNOSTICS
  Most error messages are self-explanatory. If not, run droplang with the --
  echo option and see under the respective SQL command for details. Also, any
  default connection settings and environment variables used by the libpq
  front-end library will apply.

NOTES
  Use createlang(1) to add a language.

EXAMPLES
  To remove the language pltcl:

  $ droplang pltcl dbname
