# PostgreSQL configuration file
# -----------------------------
#
# 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.
#
# 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".
