DROPLANG(1) PostgreSQL Client Applications DROPLANG(1)NAMEdroplang - remove a PostgreSQL procedural language
SYNOPSISdroplang [ connection-options... ] langname [ dbname ]
droplang [ connection-options... ] --list | -l dbname
DESCRIPTIONdroplang 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(l)]
for more.
OPTIONSdroplang accepts the following command line arguments:
langname
Specifies the name of the backend programming lan-
guage 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 respec-
tive SQL command for details. Check also under psql(1) for
more possibilities.
NOTES
Use createlang(1) to add a language.
