# 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.
