droplang
DROPLANG(1) PostgreSQL Client Applications DROPLANG(1)
NAME
droplang - remove a PostgreSQL procedural language
SYNOPSIS
droplang [ connection-options... ] langname [ dbname ]
droplang [ connection-options... ] --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(7)] 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 Displays SQL commands as they are executed.
-l
--list Shows a list of already installed languages in the target database (which must be specified).
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.
DIAGNOSTICS
Most error messages are self-explanatory. If not, run droplang with the --echo option and see under the respective SQL command for details.
Check also under psql(1) for more possibilities.
NOTES
Use createlang(1) to add a language.
EXAMPLES
To remove pltcl:
$ droplang pltcl dbname
