  5. # This file consists of lines of the form:
  6. #
  7. #   name = value
  8. #
  9. # (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
  10. # "#" anywhere on a line.  The complete list of parameter names and allowed
  11. # 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 SIGHUP
  18. # signal.  If you edit the file on a running system, you have to SIGHUP the
  19. # server for the changes to take effect, run "pg_ctl reload", or execute
  20. # "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 time
  25. # with the "SET" SQL command.
  26. #
  27. # Memory units:  kB = kilobytes        Time units:  ms  = milliseconds
  28. #                MB = megabytes                     s   = seconds
