| 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 | |
| 28 # kB = kilobytes ms = milliseconds | |
| 29 # MB = megabytes s = seconds | |
