Seeded Replication

Hi,

We are working on a project to set up replication from on premises Postgresql 10.4 to Azure Postgresql services. However, our database is about 200G and it will take a long time to complete the initial data copy. We would like to manually seed the subscriber database with data dump and then turn on the subscription like depesz showed in this post https://www.depesz.com/2017/02/07/waiting-for-postgresql-10-logical-replication/ . It works for the small testing database but when I applied same steps with entire database, I am getting "ERROR: duplicate key value violates unique constraint" errors. Basically postgresql does not recognize the primary key.

Any thought / suggestion is helpful!
