-# PostgreSQL configuration file
-# -----------------------------
-#
-# 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
-#                kB = kilobytes                     ms  = milliseconds

+# "SELECT pg_reload_conf()".  Some parameters, which are marked below,
+# require a server shutdown and restart to take effect.

-# PostgreSQL configuration file
-# -----------------------------
-#
-# 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
