+# This file consists of lines of the form:
+#
+#   name = value
+#
+# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
+# "#" anywhere on a line.  The complete list of parameter names and allowed
+# values can be found in the PostgreSQL documentation.
+#
+# The commented-out settings shown in this file represent the default values.
+# Re-commenting a setting is NOT sufficient to revert it to the default value;
+# you need to reload the server.
+#
+# This file is read on server startup and when the server receives a SIGHUP
+# signal.  If you edit the file on a running system, you have to SIGHUP the
+# server for the changes to take effect, or use "pg_ctl reload".  Some
+# parameters, which are marked below, require a server shutdown and restart to
+# take effect.
+#
+# Any parameter can also be given as a command-line option to the server, e.g.,
+# "postgres -c log_connections=on".  Some parameters can be changed at run time
+# with the "SET" SQL command.
+#
+# Memory units:  kB = kilobytes        Time units:  ms  = milliseconds
