       createlang - define a new PostgreSQL procedural language

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

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

       createlang  is  a utility for adding a new programming language to a PostgreSQL database.  createlang is just a
       wrapper around the CREATE LANGUAGE [create_language(7)] command.

       createlang accepts the following command-line arguments:

              Specifies the name of the procedural programming language to be defined.

       [-d] dbname

       [--dbname] dbname
              Specifies to which database the language should be added.  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 database.

       createlang 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 the value begins with a slash,
              it is used as the directory for the Unix domain socket.

       -p port

       --port port
              Specifies the TCP port or local Unix domain socket file extension on which the server is  listening  for

       -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 createlang to prompt for a password before connecting to a database.

              This  option is never essential, since createlang will automatically prompt for a password if the server
              demands password authentication.  However, createlang 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 createlang 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 droplang(1) to remove a language.

       To install the language pltcl into the database template1:

       $ createlang pltcl template1

       Note that installing the language into template1 will cause it to be automatically installed into subsequently-
       created databases as well.
