Uh, the default setting is an empty string. Are you sure this is
not your own error? If it isn't, perhaps it is a problem in some
packaging of Postgres, but you did not say which package you are
using.
The line looks like that after using the One-click installer
available here - http://www.enterprisedb.com/products/pgdownload.do.
Probably should be sorted out by EnterpriseDB.
I just checked the one-click 8.4rc1 installer on Ubuntu and it is fine:
#log_line_prefix = '' # special values:
so I am unclear why Windows would have a different default. How are you
viewing this default? From the command line?
I've attached the unmodified "postgresql.conf" just after a
successful installation (it is in "C:\Program
Files\PostgreSQL\8.4\data").
Connecting to the server locally with psql gives:
Server [localhost]:
Database [postgres]:
Port [5432]:
Username [postgres]:

# 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.
