11 # values can be found in the PostgreSQL documentation.

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;

23 # Any parameter can also be given as a command-line option to the server, e.g.,
