Hello, Nazir!
When I ran `meson setup build --buildtype=debugoptimized` on both my x86
machine and my arm machine, the response on both was:
"External libraries
" lz4 : NO"
However, I did not remove commit 34dfca2934 from any of my Postgres builds;
I left that commit in place.
Let me know if that helps!
And I agree, the results look nice.
Best,
-Manni
