# 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, 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::
