Sequences / Replication

[Jonathan Eastgate <jonathan.eastgate@xxxxxxxxx>]

Hi everyone.

We're seeing some odd behaviour from a PostgreSQL group - one running as primary and the other as a hot slave using streaming replication.

When a failover event occurs and we switch to the hot slave as primary sequences in tables jump by 33 - so where the last number allocated in the sequence was 100 prior to failover once adding the next entry the sequence will produce the number 133. 

https://stackoverflow.com/questions/38450394/postgresql-sequence-jump-30-or-33-number-with-cache-equals-1

I've found the following post in the forums - but any advice on how to resolve or counter this would be appreciated.

Thanks in advance.
