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!
