| # PostgreSQL configuration file |
| # ----------------------------- |
| # |
| # This file consists of lines of the form: |
| # |
| # name = value |
| # |
| # (The "=" is optional.) Whitespace may be used. Comments are introduced with |
| # "#" anywhere on a line. The complete list of parameter names and allowed |
| # values can be found in the PostgreSQL documentation. |
| # |
| # The commented-out settings shown in this file represent the default values. |
| # Re-commenting a setting is NOT sufficient to revert it to the default value; |
| # you need to reload the server. |
| # |
| # This file is read on server startup and when the server receives a SIGHUP |
| # signal. If you edit the file on a running system, you have to SIGHUP the |
| # server for the changes to take effect, or use "pg_ctl reload". Some |
| # parameters, which are marked below, require a server shutdown and restart to |
| # take effect. |
| # |
| # Any parameter can also be given as a command-line option to the server, e.g., |
| # "postgres -c log_connections=on". Some parameters can be changed at run time |
| # with the "SET" SQL command. |

| # Memory units: kB = kilobytes Time units: ms = milliseconds |
