Could you please tell me do I need to reinitialize the hot standby server after I upgrade to the latest version? In the release logs it says a fresh base backup is only needed if the version is 9.1.10, but I had 9.1.9 and still had a related issue. I didn't power off Postgres on the stand by after I made a new fresh base backup.
We also have a hot standby server running 9.2.4 which shouldn't be affected and which was never powered of from first start, so I guess that server doesn't need to be reinitialized?
