NAME

       createlang - define a new PostgreSQL procedural language

SYNOPSIS

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

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

DESCRIPTION

       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.

OPTIONS

       createlang accepts the following command-line arguments:

       langname
	      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 sys-
	      tem user.

       -e

       --echo Display SQL commands as they are executed.

       -l

       --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.

       -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 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 authentica-
	      tion.   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.

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 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.

NOTES

       Use droplang(1) to remove a language.

EXAMPLES

       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.
