Hi Yansang, I'm sorry you didn't see a reply - EDB's support and pre-sales team would be happy to help you assist you in migrating your application and tuning your Postgres server to be optimized for your application's workloads. I know we are working with many people at your organization, but I do not see your name on our list of contacts. I humbly request you to reach out direct to our teams at sales@xxxxxxxxxxxxxxxx or speak with the people who have used support@xxxxxxxxxxxxxxxx to make sure we provide you with the highest quality support (Our teams don't always monitor these mailing-lists). We do look forward to working with you! -Jason Davis -- View this message in context: http://postgresql.nabble.com/PPAS-capacity-measuring-method-tp5884774p5885196.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
