Hi, I've setup 2 nodes for streaming replication and it was working perfectly. I the tested multiple failovers, switching master/slave, and now the streaming replication doesn't work anymore. I had a look at the log and it seems fine "LOG: replication connection authorized: user=postgres ...". From ps, the sender and receiver processes have been started. However there is something strange with the sender process, ps says: postgres: wal sender process postgres xxx.xxx.xxx.xxx (48159) startup And the streaming never starts. What are the possible problems?
