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