That is what? 38GB of RAM?

7165704 / 8 = 895713

So counting variations, I would say 875000. That is a 8GB box, right? So 875000
is about 7000MB. Which should be rather practical. Of course you can give it
everything you can but that's upto you.

Can you get explain analze for inserts? I think some foreign key check etc. are
taking long and hence it accumulates. But that is just a wild guess.

Off the top of my head, you have allocated roughly 48K shard buffers which seems
bit on higher side. Can you check with something like 10K-15K?
