# 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.

# 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.
