NAME

6       createlang - install a PostgreSQL procedural language
7

SYNOPSIS

9       createlang [connection-option...] langname [dbname]
10
11       createlang [connection-option...] --list | -l  [dbname]
12

DESCRIPTION

14       createlang is a utility for adding a procedural language to a
15       PostgreSQL database.
16
17       createlang is just a wrapper around the CREATE EXTENSION
18       (CREATE_EXTENSION(7)) SQL command.
19
20           Caution
21           createlang is deprecated and may be removed in a future PostgreSQL
22           release. Direct use of the CREATE EXTENSION command is recommended
23           instead.
24

OPTIONS

26       createlang accepts the following command-line arguments:
27
28       langname
29           Specifies the name of the procedural language to be installed.
30           (This name is lower-cased.)
31
32       [-d] dbname, [--dbname=]dbname
33           Specifies the database to which the language should be added. The
34           default is to use the database with the same name as the current
35           system user.
36
37       -e, --echo
38           Display SQL commands as they are executed.
39
40       -l, --list
41           Show a list of already installed languages in the target database.
42
43       -V, --version
44           Print the createlang version and exit.
45
46       -?, --help
47           Show help about createlang command line arguments, and exit.
48
49       createlang also accepts the following command-line arguments for
50       connection parameters:
51
52       -h host, --host=host
53           Specifies the host name of the machine on which the server is
54           running. If the value begins with a slash, it is used as the
55           directory for the Unix domain socket.
56
57       -p port, --port=port
58           Specifies the TCP port or local Unix domain socket file extension
59           on which the server is listening for connections.
60
61       -U username, --username=username
62           User name to connect as.
63
64       -w, --no-password
65           Never issue a password prompt. If the server requires password
66           authentication and a password is not available by other means such
67           as a .pgpass file, the connection attempt will fail. This option
68           can be useful in batch jobs and scripts where no user is present to
69           enter a password.
70
71       -W, --password
72           Force createlang to prompt for a password before connecting to a
73           database.
74
75           This option is never essential, since createlang will automatically
76           prompt for a password if the server demands password
77           authentication. However, createlang will waste a connection attempt
78           finding out that the server wants a password. In some cases it is
79           worth typing -W to avoid the extra connection attempt.
80

ENVIRONMENT

82       PGDATABASE, PGHOST, PGPORT, PGUSER
83           Default connection parameters
84
85       This utility, like most other PostgreSQL utilities, also uses the
86       environment variables supported by libpq (see Section 31.14,
87       “Environment Variables”, in the documentation).
88

DIAGNOSTICS

90       Most error messages are self-explanatory. If not, run createlang with
91       the --echo option and see the respective SQL command for details. Also,
92       any default connection settings and environment variables used by the
93       libpq front-end library will apply.
94

NOTES

96       Use droplang(1) to remove a language.
97

EXAMPLES

99       To install the language pltcl into the database template1:
100
101           $ createlang pltcl template1
102
103       Note that installing the language into template1 will cause it to be
104       automatically installed into subsequently-created databases as well.
