I just don't get what all this fuss is about trying to get PG up on the smallest possible values for shared_buffers, especially considering this person has 1 TB of memory?
The fuss is why he can't make it bigger. No one wants to make it as small as possible.

Here is shmall:
kernel.shmall = 17179869184
How did that get so small? On my Ubuntu18.04, it comes out of the box at 2^64 - 1. Why would anyone have set about making it smaller? Now the current value should still be big enough, but I wonder what else got changed while someone was monkeying with things that didn't need to be monkeyed with.
