Another advantage of using pglogical, over other solutions (cough, DMS), is that it allows you to replicate the current value of a sequence; rather than having to update all those values, post failover.
SELECT pglogical.replication_set_add_sequence('default', 'foo.foo_id_seq');
It is important to understand how it is implemented though:
We periodically capture state current state of the sequence and send update to the replication queue with some additional buffer. This means that in normal situation the sequence values on subscriber will be ahead of those on provider
This can be a bit of a surprise when you check if the replication is working!
Look on my works, ye Mighty, and despair!
