B91: Started streaming WAL from primary

Example Postgres Log Output:

LOG: started streaming WAL from primary at 4E8/9E000000 on timeline 6

LOG: restarted WAL streaming at 3E/62000000 on timeline 3

Explanation:

This log event indicates that the standby server has switched from archive recovery (or a base backup download) to streaming replication.

You would typically see this once the follower has caught up enough that the primary still has all WAL segments available for the follower.

Recommended Action:

No action needed, this event indicates that streaming replication is working.
