Problem to use remote cygwin server using ssh and native psql 8.3.5

I have installed cycwin and sshd in my Windows server.

I have Winnative psql.exe (8.3.5)

If I use cygwin locally in this server and give command in cygwin session:
psql -h somehost -U someuser -d somedb
it works fine

But if i use via ssh same way, then no echo ... and process hang.

I have tested remote ssh and local

Cygwin session
ssh localhost
=> connect local, ...
psql -h somehost -U someuser -d somedb
will hang

Cygwin old native psql 8.2 works, but I like to use newer psql = Win
native psql.exe

tested using Cygwin 1.5.x and 1.7.x

Ssh tty problem using Windows native psql.exe ?
