   9 # PostgreSQL configuration file
  10 # -----------------------------
  11 #
  12 # This file consists of lines of the form:
  13 #
  14 #   name = value
  15 #
  16 # (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
  17 # "#" anywhere on a line.  The complete list of parameter names and allowed
  18 # values can be found in the PostgreSQL documentation.
  19 #
  20 # The commented-out settings shown in this file represent the default values.
  21 # Re-commenting a setting is NOT sufficient to revert it to the default value;
  22 # you need to reload the server.
  23 #
  24 # This file is read on server startup and when the server receives a SIGHUP
  25 # signal.  If you edit the file on a running system, you have to SIGHUP the
  26 # server for the changes to take effect, run "pg_ctl reload", or execute
  27 # "SELECT pg_reload_conf()".  Some parameters, which are marked below,
  28 # require a server shutdown and restart to take effect.
  29 #
  30 # Any parameter can also be given as a command-line option to the server, e.g.,
  31 # "postgres -c log_connections=on".  Some parameters can be changed at run time
  32 # with the "SET" SQL command.
