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.
