2 # PostgreSQL configuration file

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