Discussed verbally with Kostja. Agreed that even though there are some
concerns regarding the watcher API re-usability and efficiency, we shall
push it as is now and rework it later if we need to.

I added a comment to patch #4 (see below) and pushed all the patches to
1.10-features.

+/**
+ * Notify all interested watchers about a WAL event.
+ *
+ * XXX: Note, this function iterates over all registered watchers,
+ * including those that are not interested in the given event.
+ * This is OK only as long as the number of events/watchers is
+ * small. If this ever changes, we should consider maintaining
+ * a separate watcher list per each event type.
+ */
 static void
 wal_notify_watchers(struct wal_writer *writer, unsigned events)
