       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 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 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.
