- silent_mode configuration parameter

- Runs the server silently. If this parameter is set, the server
- will automatically run in background and disassociate from the
- controlling terminal.
- This parameter can only be set at server start.
-
-
-
-
- When this parameter is set,
- the server's standard output and standard error are redirected
- to the file postmaster.log within the data directory.
- There is no provision for rotating this file, so it will grow
- indefinitely unless server log output is redirected elsewhere
- by other settings. It is recommended that log_destination
- be set to syslog or that logging_collector be
- enabled when using this option. Even with those measures, errors
- reported early during startup may appear in
- postmaster.log rather than the normal log destination.
