2# PostgreSQL configuration file
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: kB = kilobytes Time units: ms = milliseconds
28# MB = megabytes s = seconds
