You can query gucs with -C. E.g. postgres -D pgdev-dev -c shared_buffers=16MB -C shared_memory_size_in_huge_pages 13 postgres -D pgdev-dev -c shared_buffers=16MB -c huge_page_size=1GB -C shared_memory_size_in_huge_pages 1 Which is very useful to be able to actually configure that number of huge pages. I don't think a system view or such would not help here. Greetings, Andres Freund
