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(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
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
