I set 1960MB successfully for maintenance_work_mem, and got about 30% performance improvement on my COPY batch inserts.
So I’m trying to run the import with even more mem (my machine has 32GB).
Problem: Whenever I set any greater value, eg 2500MB, the postgres x64 server won’t start up.
Do I have to configure another property? Or is it just not supported to give the mem values of 2GB+?
