   6 #
   7 #   name = value
   8 #
   9 # (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
  10 # "#" anywhere on a line.  The complete list of parameter names and allowed
  11 # values can be found in the PostgreSQL documentation.
  12 #
  13 # The commented-out settings shown in this file represent the default values.
  14 # Re-commenting a setting is NOT sufficient to revert it to the default value;
  15 # you need to reload the server.
  16 #
  17 # This file is read on server startup and when the server receives a SIGHUP
  18 # signal.  If you edit the file on a running system, you have to SIGHUP the
  19 # server for the changes to take effect, or use "pg_ctl reload".  Some
  20 # parameters, which are marked below, require a server shutdown and restart to
  21 # take effect.
  22 #
  23 # Any parameter can also be given as a command-line option to the server, e.g.,
  24 # "postgres -c log_connections=on".  Some parameters can be changed at run time
  25 # with the "SET" SQL command.
