|
||||||
$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
