+#
+# This file consists of lines of the form:
+#
+#   name = value
+#
+# (The '=' is optional.) White space may be used. Comments are introduced
+# with '#' anywhere on a line. The complete list of option names and
+# allowed values can be found in the PostgreSQL documentation. The
+# commented-out settings shown in this file represent the default values.
+#
+# Please note that re-commenting a setting is NOT sufficient to revert it
+# to the default value, unless you restart the postmaster.
+#
+# Any option can also be given as a command line switch to the
+# postmaster, e.g. 'postmaster -c log_connections=on'. Some options
+# can be changed at run-time with the 'SET' SQL command.
+#
+# This file is read on postmaster startup and when the postmaster
+# receives a SIGHUP. If you edit the file on a running system, you have 
+# to SIGHUP the postmaster for the changes to take effect, or use 
+# "pg_ctl reload". Some settings, such as listen_addresses, require
+# a postmaster shutdown and restart to take effect.
