+1, emphatically. XLogInsert is a really nasty scalability bottleneck. We need to move as much logic out of that function as possible, and particularly out from under WALInsertLock.
Andres' patch was applied, so not sure what you mean by +1ing a comment made in relation to that patch.
I'm aware that WALInsertLock is a bottleneck and am not going to be making that worse.
