 # -----------------------------
 # 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.
 #
 # Memory units:  B  = bytes            Time units:  us  = microseconds

 #                MB = megabytes                     s   = seconds
 #                GB = gigabytes                     min = minutes
 #                TB = terabytes                     h   = hours
