Thanks, Vik for sharing feedback. So, here is a summarization of what different people think: Option-1: Vik Option-2: Alvaro, Magnus Option-3: Michael, Hari Option-4: Amit, Hari, Magnus We still can't conclude clearly, but I think Option-2 and Option-4 are the ones which appear to be more popular. Does anyone else want to weigh in here? If no more people share an opinion, I will go with one among Option-2 or Option-4. -- With Regards, Amit Kapila. EnterpriseDB: http://www.enterprisedb.com
