Hi all,

I found an error: on 32bit system (I tested on Debian 6.1.0-32-686-pae #1 SMP PREEMPT_DYNAMIC Debian 6.1.129-1 (2025-03-06) i686 GNU/Linux) when we set huge_page_size = 1 TB postgres process fails with signal SIGFPE when calculated hugepagesize_local = (Size) huge_page_size * 1024; the value exceeds max for unsigned int = (2^32 – 1).
I attached a full backtrace and one small fix.

What do you think about this?
Thank you for your attention!
