Whitespace may be used.  Comments are introduced with10# "#" anywhere on a line.  The complete list of parameter names and allowed11# 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 SIGHUP18# signal.  If you edit the file on a running system, you have to SIGHUP the19# server for the changes to take effect, run "pg_ctl reload", or execute20# "SELECT pg_reload_conf()".  Some parameters, which are marked below,21# require a server shutdown and restart to 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 time25# with the "SET" SQL command.26#27# Memory units:  B  = bytes            Time units:  us  = microseconds28#                kB = kilobytes                     ms  = milliseconds29#                MB = megabytes                     s   = seconds30#                GB = gigabytes                     min = minutes31#                TB = terabytes                     h   = hours32#                                                   d   = days33 34 35#------------------------------------------------------------------------------36# FILE LOCATIONS37#------------------------------------------------------------------------------38 39# The default values of these variables are driven from the -D command-line40# option or PGDATA environment variable, represented here as ConfigDir.41 42#data_directory = 'ConfigDir'		# use data in another directory43					# (change requires restart)44#hba_file = 'ConfigDir/pg_hba.conf'	# host-based authentication file45					# (change requires restart)46#ident_file = 'ConfigDir/pg_ident.conf'	# ident configuration file47					# (change requires restart)48 49# If external_pid_file is not explicitly set, no extra PID file is written.50#external_pid_file = ''			# write an extra PID file51					# (change requires restart)52 53 54#------------------------------------------------------------------------------55# CONNECTIONS AND AUTHENTICATION56#------------------------------------------------------------------------------57 58# - Connection Settings -59 60#listen_addresses = 'localhost'		# what IP address(es) to listen on;61					# comma-separated list of addresses;62					# defaults to 'localhost';
