| 3 | # ----------------------------- |
| 4 | # |
| 5 | # This file consists of lines of the form: |
| 6 | # |
| 7 | # name = value |
| 8 | # |
| 9 | # (The "=" is optional.) Whitespace may be used. Comments are introduced with |
| 10 | # "#" anywhere on a line. The complete list of parameter names and allowed |
| 11 | # values can be found in the PostgreSQL documentation. |
| 12 | # |
| 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; |
| 15 | # you need to reload the server. |
| 16 | # |
| 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 |
| 25 | # with the "SET" SQL command. |
| 26 | # |
| 27 | # Memory units: B = bytes Time units: us = microseconds |
