HOW TO GET initdb WORKING WITH CYGWIN (if you're getting signal 12's)

I was having trouble with signal 12's. Lots of people have the problem. A
recipe to fix is on top. A log of an erroneous trial and a successful trial
are below...

These are cleaned up instructions. I got help from this message:
http://archives.postgresql.org/pgsql-bugs/2004-11/msg00174.php

# run cygserver-config
> cygserver-config

# start the cygserver
> cygrunsrv -S cygserver

# set the CYGWIN environment variable
> export CYGWIN=server

# unset the LANG environment variable
> unset LANG

# check [Control Panel] -> [Administrative Tools] ->
# [Services]. Should have a Service with name "CYGWIN cygserver"
# with STATUS = "Started"

# run initdb
> initdb -d -D /cygdrive/e/david/pgdata

Generating /etc/cygserver.conf file

Warning: The following function requires administrator privileges!

Do you want to install cygserver as service?
(Say "no" if it's already installed as service) (yes/no) yes

The service has been installed under LocalSystem account.
To start it, call `net start cygserver' or `cygrunsrv -S cygserver'.

Further configuration options are available by editing the configuration
file /etc/cygserver.conf. Please read the inline information in that
file carefully. The best option for the start is to just leave it alone.

Please keep in mind, that a client application which wants to use
the services provided by cygserver *must* have the environment variable
CYGWIN set so that it contains the word "server". So, if you don't
need any other special CYGWIN setting, just set it to "server".

It is advisable to add this setting to the Windows system environment.

Basic Cygserver configuration finished. Have fun!
