# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form
#
#   name = value
#
# (The `=' is optional.) White space is collapsed, comments are
# introduced by `#' 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.
