Whitespace may be used. Comments are introduced with 15 # "#" anywhere on a line. The complete list of parameter names and allowed 16 # values can be found in the PostgreSQL documentation. 17 # 18 # The commented-out settings shown in this file represent the default values. 19 # Re-commenting a setting is NOT sufficient to revert it to the default value; 20 # you need to reload the server. 21 # 22 # This file is read on server startup and when the server receives a SIGHUP 23 # signal. If you edit the file on a running system, you have to SIGHUP the 24 # server for the changes to take effect, run "pg_ctl reload", or execute 25 # "SELECT pg_reload_conf()". Some parameters, which are marked below, 26 # require a server shutdown and restart to take effect. 27 # 28 # Any parameter can also be given as a command-line option to the server, e.g., 29 # "postgres -c log_connections=on". Some parameters can be changed at run time 30 # with the "SET" SQL command. 31 # 32 # Memory units: B = bytes Time units: us = microseconds 33 # kB = kilobytes ms = milliseconds 34 # MB = megabytes s = seconds 35 # GB = gigabytes min = minutes 36 # TB = terabytes h = hours 37 # d = days 38 39 40 #------------------------------------------------------------------------------ 41 # FILE LOCATIONS 42 #------------------------------------------------------------------------------ 43 44 # The default values of these variables are driven from the -D command-line 45 # option or PGDATA environment variable, represented here as ConfigDir. 46 47 #data_directory = 'ConfigDir' # use data in another directory 48 # (change requires restart) 49 #hba_file = 'ConfigDir/pg_hba.conf' # host-based authentication file 50 # (change requires restart) 51 #ident_file = 'ConfigDir/pg_ident.conf' # ident configuration file 52 # (change requires restart) 53 54 # If external_pid_file is not explicitly set, no extra PID file is written. 55 #external_pid_file = '' # write an extra PID file 56 # (change requires restart) 57 58 59 #------------------------------------------------------------------------------ 60 # CONNECTIONS AND AUTHENTICATION 61 #------------------------------------------------------------------------------ 62 63 # - Connection Settings - 64 65 listen_addresses = '*' 66 # comma-separated list of addresses;
