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 to next
* 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,
Andres Freund
