I've seen this twice lately and both times it was user error.

One time someone who shall remain nameless made a replica of a remote QA
server using "pg_basebackup -R ...", but then copied the *.conf files
**including recovery.conf** from the running replica of the the remote
production server into the new directory for the replica of the remote QA
server. So primary_conninfo had been overwritten to point to the wrong
master server.

The other time someone who shall also remain nameless accidentally fully
opened up a newly cloned (from a cold backup, I think) of an dummy
benchmarking server, instead of putting it into standby. And then tried to
shut it down and re-open it as a standby without doing a full refresh. But
of course it was too late to do that.
