# 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, or use "pg_ctl reload".  Some
20
# parameters, which are marked below, require a server shutdown and restart to
21
# 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.
