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