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 procedural language from
       a PostgreSQL database.

       droplang is just a wrapper around the DROP EXTENSION
       (DROP_EXTENSION(7)) SQL command.

           Caution
           droplang is deprecated and may be removed in a future PostgreSQL
           release. Direct use of the DROP EXTENSION command is recommended
           instead.

OPTIONS

       droplang accepts the following command line arguments:

       langname
           Specifies the name of the procedural 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.

       -V, --version
           Print the droplang version and exit.

       -?, --help
           Show help about droplang command line arguments, and exit.

       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, --no-password
           Never issue a password prompt. If the server requires password
           authentication and a password is not available by other means such
           as a .pgpass file, the connection attempt will fail. This option
           can be useful in batch jobs and scripts where no user is present to
           enter a password.

       -W, --password
           Force droplang to prompt for a password before connecting to a
           database.

           This option is never essential, since droplang will automatically
           prompt for a password if the server demands password
           authentication. However, droplang will waste a connection attempt
           finding out that the server wants a password. In some cases it is
           worth typing -W to avoid the extra connection attempt.

ENVIRONMENT

       PGDATABASE, PGHOST, PGPORT, PGUSER
           Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses the
       environment variables supported by libpq (see Section 31.13,
       "Environment Variables", 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
