  6. # This file consists of lines of the form:
  7. #
  8. #   name = value
  9. #
  10. # (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
  11. # "#" anywhere on a line.  The complete list of parameter names and allowed
  12. # values can be found in the PostgreSQL documentation.
  13. #
  14. # The commented-out settings shown in this file represent the default values.
  15. # Re-commenting a setting is NOT sufficient to revert it to the default value;
  16. # you need to reload the server.
  17. #
  18. # This file is read on server startup and when the server receives a SIGHUP
  19. # signal.  If you edit the file on a running system, you have to SIGHUP the
  20. # server for the changes to take effect, or use "pg_ctl reload".  Some
  21. # parameters, which are marked below, require a server shutdown and restart to
  22. # take effect.
  23. #
  24. # Any parameter can also be given as a command-line option to the server, e.g.,
  25. # "postgres -c log_connections=on".  Some parameters can be changed at run time
  26. # with the "SET" SQL command.
  27. #
  28. # Memory units:  kB = kilobytes        Time units:  ms  = milliseconds
