Btw, I find the 'you' used in the comment somewhat irritating. Not badly
so, but reading something like:
* When you are about to write* out WAL, it is important to call WaitXLogInsertionsToFinish() *before** acquiring
WALWriteLock,to avoid deadlocks. Otherwise you might get stuck* waiting for an insertion to finish (or at least advance
tonext* uninitialized page), while you're holding WALWriteLock.
 

just seems strange to me. If this directed at plugin authors, maybe, but
it really isn't...

But that's probably a question for a native speaker...

Greetings,
