+ else if (source == XLOG_FROM_STREAM)
+ ereport(LOG,
+ (errmsg("recovering WAL segment \"%s\" received from primary",
+ xlogfname)));
This is incorrect when using a cascading standby. And perhaps this
could use a switch/case?

While quickly testing, I got reminded that the LOG for a segment
retrieved from the local pg_wal would generate some noise when running
for example the bootstrap process. Is this one really interesting
compared to the two others?
