13 | # The commented-out settings shown in this file represent the default values. |

19 | # server for the changes to take effect, or use "pg_ctl reload". Some |
---|
20 | # parameters, which are marked below, require a server shutdown and restart to |
---|
21 | # 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 |
