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 can handle all the languages  supplied
       in  the  default PostgreSQL distribution, but not languages provided by
       other parties.

       Although backend programming languages can be added directly using sev-
       eral  SQL commands, it is recommended to use createlang because it per-
       forms a number of checks and is much easier to use. See CREATE LANGUAGE
       [create_language(7)] for additional information.


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
              system user.

       -e

       --echo Display SQL commands as they are executed.

       -l

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

       -L directory
              Specifies  the directory in which the language interpreter is to
              be found. The directory is normally  found  automatically;  this
              option is primarily for debugging purposes.


       createlang  also  accepts the following command-line arguments for con-
       nection 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  exten-
              sion on which the server is listening for connections.

       -U username

       --username username
              User name to connect as.

       -W

       --password
              Force password prompt.



ENVIRONMENT

       PGDATABASE

       PGHOST

       PGPORT

       PGUSER Default connection parameters


DIAGNOSTICS

       Most  error  messages are self-explanatory. If not, run createlang with
       the --echo option and see under the respective SQL command for details.


NOTES

       Use droplang(1) to remove a language.


EXAMPLES

       To install the language pltcl into the database template1:

       $ createlang pltcl template1
