    9 # (The '=' is optional.) White space may be used. Comments are introduced
    10 # with '#' anywhere on a line. The complete list of option names and
    11 # allowed values can be found in the PostgreSQL documentation. The
    12 # commented-out settings shown in this file represent the default values.
    13 #
    14 # Please note that re-commenting a setting is NOT sufficient to revert it
    15 # to the default value, unless you restart the postmaster.
    16 #
    17 # Any option can also be given as a command line switch to the
    18 # postmaster, e.g. 'postmaster -c log_connections=on'. Some options
    19 # can be changed at run-time with the 'SET' SQL command.

    21 # This file is read on postmaster startup and when the postmaster
    22 # receives a SIGHUP. If you edit the file on a running system, you have
    23 # to SIGHUP the postmaster for the changes to take effect, or use
    24 # "pg_ctl reload". Some settings, such as listen_addresses, require
    25 # a postmaster shutdown and restart to take effect.

     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 paramters can be changed at run time
     25# with the "SET" SQL command.
