| 9 | # (The "=" is optional.) Whitespace may be used. Comments are introduced with |

| 11 | # values can be found in the PostgreSQL documentation. |
|---|
| 12 | # |

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

| 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 |
