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.

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.,
