10 # (The "=" is optional.) Whitespace may be used. Comments are introduced with
11 # "#" anywhere on a line. The complete list of parameter names and allowed
12 # values can be found in the PostgreSQL documentation.
14 # The commented-out settings shown in this file represent the default values.
15 # Re-commenting a setting is NOT sufficient to revert it to the default value;
16 # you need to reload the server.
18 # This file is read on server startup and when the server receives a SIGHUP
19 # signal. If you edit the file on a running system, you have to SIGHUP the
20 # server for the changes to take effect, or use "pg_ctl reload". Some
21 # parameters, which are marked below, require a server shutdown and restart to
24 # Any parameter can also be given as a command-line option to the server, e.g.,
25 # "postgres -c log_connections=on". Some parameters can be changed at run time
26 # with the "SET" SQL command.
