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
32# d = days
