Hi, 

What exactly does the postgres: writer process ??  Only on one of the servers the reported time of this process always rises very much(in this example 32 Hours....) and the postgresql ist was restarted 2 days ago. I find it odd, because I have this behavior only on one system. Is this normal? 

I have also a replication on one of the dbs.
