Re: shmget problem with Win NT services

Hi Attila,

Probably the best place to ask is on the PostgreSQL "Cygwin" mailing
list, as the people there specialise in Cygwin/Windows knowledge. Much
of the PostgreSQL Community has stronger knowledge of non-Windows
environments.

You can join that mailing list by going to:

http://developer.postgresql.org/mailsub.php

Hope that helps.

Regards and best wishes,

Justin Clift
