pg_hba.conf password authentication problem - Mailing list pgsql-general

Hi,
   I am using postgresql7.0.2 compiled using cygwinb20 on
WinNT.Previously I was using postgres-6.5.3.
   The password based authentication is not working anymore.while
checking the mail archive I noticed someone else also had this problem.
So far I didn't see any workaround in the mail archive
   This link
http://www.postgresql.org/mhonarc/pgsql-general/2000-05/msg00809.html
suggested that after doing initdb the users have to be created with
passwords.
   Well after doing that it still doesn't authenticate based on the
password stored in pg_shadow.
While running postmaster in debug mode.I get these results
---------------------PSQL Client----------------------
bash-2.02$ psql -h localhost -U pkdhar testdb
Password:
psql: pqReadData() -- backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally
        before or while processing the request.

   Any clues I might be missing here?????
Also I did a regression test on cygwin b20. There is some stuff which
doesn't work in NT i.e. timestamp,abstime ,transactions ,select etc.
Here is the regress.out result.

=============== Notes...                              =================
postmaster must already be running for the regression tests to succeed.
The time zone is set to PST8PDT for these tests by the client frontend.
Please report any apparent problems to ports@postgresql.org
See regress/README for more information.
