pg_dump is filling C: drive up to 100 percent

Hi team,

pg_dump  is filling C:\

This is for postgres version 12. Binary directory, data directory are in E:\

I’m redirecting pg_dump output also to E:\, I was taking a tar dump output.

But C:\ is getting filled up . Looks like it is used for some sort of temporary staging.

Is there a way not to use C:\ for this?

Regards,
