help="\
|
||||
$CMDNAME is a utility to start, stop, restart, reload configuration files,
|
||||
or report the status of a PostgreSQL server.
|
||||
|
||||
Usage:
|
||||
$CMDNAME start [-w] [-D DATADIR] [-s] [-l FILENAME] [-o \"OPTIONS\"]
|
||||
$CMDNAME stop [-W] [-D DATADIR] [-s] [-m SHUTDOWN-MODE]
|
||||
$CMDNAME restart [-w] [-D DATADIR] [-s] [-m SHUTDOWN-MODE] [-o \"OPTIONS\"]
|
||||
$CMDNAME reload [-D DATADIR] [-s]
|
||||
$CMDNAME status [-D DATADIR]
|
||||
|
||||
Common options:
|
||||
-D DATADIR location of the database storage area
|
||||
-s only print errors, no informational messages
|
||||
-w wait until operation completes
|
||||
-W do not wait until operation completes
|
||||
--help show this help, then exit
|
||||
--version output version information, then exit
|
||||
(The default is to wait for shutdown, but not for start or restart.)
|
||||
|
||||
If the -D option is omitted, the environment variable PGDATA is used.
|
||||
|
||||
Options for start or restart:
|
||||
-l FILENAME write (or append) server log to FILENAME. The
|
||||
use of this option is highly recommended.
|
||||
-o OPTIONS command line options to pass to the postmaster
|
||||
(PostgreSQL server executable)
|
||||
-p PATH-TO-POSTMASTER normally not necessary
|
||||
|
||||
Options for stop or restart:
|
||||
-m SHUTDOWN-MODE may be 'smart', 'fast', or 'immediate'
|
||||
|
||||
Shutdown modes are:
|
||||
smart quit after all clients have disconnected
|
||||
fast quit directly, with proper shutdown
|
||||
immediate quit without complete shutdown; will lead to recovery on restart

||||
