+#
+# 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, run "pg_ctl reload", or execute
+# "SELECT pg_reload_conf()". 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: B = bytes Time units: us = microseconds
