With current limits, the most bgwriter can do (with 8k pages) is 1000 pages

FWIW, I think working on replacing bgwriter (e.g. by working on the
patch I send with a POC replacement) wholesale is a better approach than
spending time increasing limits.

Do you have a link to that? I'm not seeing anything in the archives.
