       droplang - remove a PostgreSQL procedural language


       droplang [ connection-option... ]  langname [ dbname ]

       droplang [ connection-option... ]   [ --list ]  [ -l ]  dbname


       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.


       droplang accepts the following command line arguments:

              Specifies the name of the backend  programming  language  to  be

       [-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.


       --echo Display SQL commands as they are executed.


       --list Show  a  list  of  already  installed  languages  in  the target

       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.


              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.


              Force  droplang  to prompt for a password before connecting to a

              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.





       PGUSER Default connection parameters

       This  utility,  like  most  other  PostgreSQL  utilities, also uses the
       environment variables supported by libpq (see in the documentation).


       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.


       Use createlang(1) to add a language.


       To remove the language pltcl:

       $ droplang pltcl dbname


       createlang(1), DROP LANGUAGE [drop_language(7)]
