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

       --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 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
