3 | # PostgreSQL configuration file | |
4 | # ----------------------------- | |
5 | # | |
6 | # This file consists of lines of the form: | |
7 | # | |
8 | # name = value | |
9 | # | |
10 | # (The "=" is optional.) Whitespace may be used. Comments are introduced with | |
11 | # "#" anywhere on a line. The complete list of parameter names and allowed | |
12 | # values can be found in the PostgreSQL documentation. | |
13 | # | |
14 | # The commented-out settings shown in this file represent the default values. | |
15 | # Re-commenting a setting is NOT sufficient to revert it to the default value; | |
16 | # you need to reload the server. | |
17 | # | |
18 | # This file is read on server startup and when the server receives a SIGHUP | |
19 | # signal. If you edit the file on a running system, you have to SIGHUP the | |
20 | # server for the changes to take effect, run "pg_ctl reload", or execute | |
21 | # "SELECT pg_reload_conf()". Some parameters, which are marked below, | |
22 | # require a server shutdown and restart to take effect. | |
23 | # | |
24 | # Any parameter can also be given as a command-line option to the server, e.g., | |
25 | # "postgres -c log_connections=on". Some parameters can be changed at run time | |
26 | # with the "SET" SQL command. | |
27 | # | |
28 | # Memory units: kB = kilobytes Time units: ms = milliseconds | |
29 | # MB = megabytes s = seconds | |
30 | # GB = gigabytes min = minutes | |
31 | # TB = terabytes h = hours | |
