pgagent(1) General Commands Manual pgagent(1)NAME
pgAgent - a job scheduler for PostgreSQL.
SYNOPSIS
pgagent [-f | -t seconds | -r seconds | -l number] {<connect string>}
DESCRIPTION
Introduced in pgAdmin III v1.4, pgAgent is a job scheduling agent for PostgreSQL, capable of running multi-step batch/shell and SQL tasks
on complex schedules.
Full documentation of pgAgent is available in pgAdmin III's online help. Launch pgAdmin III (simply type pgadmin3 at command prompt) and
select "Help..." from the "Help" menu. Browse through the pgAdmin III documentation until you find "pgAgent". Both database setup and sys-
tem part of the installation are detailed. You will also find instructions to create jobs and schedules.
OPTIONS -f run in the foreground (do not detach from the terminal)
-t seconds
poll time interval in seconds (default 10)
-r seconds
retry period after connection abort in seconds (>=10, default 30)
-l verbosity
logging verbosity (ERROR=0, WARNING=1, DEBUG=2, default 0)
<connect string>
The connect string required is a standard PostgreSQL libpq connection string (see the PostgreSQL documentation for further details).
For example, the following command line will run pgAgent against a server listening on the localhost, using a database called 'pgad-
min', connecting as the user 'postgres': /usr/bin/pgagent hostaddr=127.0.0.1 dbname=pgadmin user=postgres

DROPLANG(1) PostgreSQL 9.2.7 Documentation DROPLANG(1)NAME
droplang - remove a PostgreSQL procedural language
SYNOPSIS
droplang [connection-option...] langname [dbname]
droplang [connection-option...] --list | -l [dbname]
DESCRIPTION
droplang is a utility for removing an existing procedural language from a PostgreSQL database.
droplang is just a wrapper around the DROP EXTENSION (DROP_EXTENSION(7)) SQL command.
Caution
droplang is deprecated and may be removed in a future PostgreSQL release. Direct use of the DROP EXTENSION command is recommended
instead.
OPTIONS
droplang accepts the following command line arguments:
langname
Specifies the name of the procedural language to be removed. (This name is lower-cased.)
[-d] dbname, [--dbname=]dbname
Specifies from which database the language should be removed. 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.
-V, --version
Print the droplang version and exit.
-?, --help
Show help about droplang command line arguments, and exit.
droplang 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 host begins with a slash, it is used as the directory for the
Unix domain socket.
-p port, --port=port
Specifies the Internet TCP/IP 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 droplang to prompt for a password before connecting to a database.
This option is never essential, since droplang will automatically prompt for a password if the server demands password authentication.
However, droplang 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 Section 31.14, "Environment
Variables", in the documentation).
DIAGNOSTICS
Most error messages are self-explanatory. If not, run droplang 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 createlang(1) to add a language.
EXAMPLES
To remove the language pltcl:
$ droplang pltcl dbname
