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 per-
       forms  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  connec-
       tion 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  direc-
              tory 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.


NOTES

       Use createlang(1) to add a language.


EXAMPLES

       To remove the language pltcl:

       $ droplang pltcl dbname
