If you want help with that, you will have to give us enough information to explain what
happened.
- What exactly is a "replication interruption", and how do you diagnose it?
- Are you using streaming replication or logical replication?
- If it is streaming replication, are you using a replication slot?
- It is expected that if you suspend replication and have a replication slot, WAL will
pile up on the primary. But what is the connection with pg_basebackup?
