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
several SQL commands, it is recommended to use
createlang because it performs a number
of checks and is much easier to use. See
for additional information.
Optionscreatelang accepts the following command-line arguments:
langname
Specifies the name of the procedural programming language to be
defined.
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.
Display SQL commands as they are executed.
Show a list of already installed languages in the target database.
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 connection parameters:
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.
Specifies the TCP port or local Unix domain socket file
extension on which the server
is listening for connections.
User name to connect as.
Force password prompt.
