Re: /usr/bin/postmaster -D /usr/local/pgsql/data RESULTS IN A CORE DUMP

This topic on the pgsql-cygwin maillist helped me a lot to solve my problem:
http://archives.free.net.ph/message/20050807.152333.9a9e2d10.en.html

I got one of the latest snapshots of the cygwin1.dll and now postmaster works.

Best Regards,
Vladimir
