Thanks for feedback!

Do we know of any such products or users?

I found an OS that runs on many 32-bit chips, FreeRTOS, that seems quite popular.
Couldn't find anything about PostgreSQL and FreeRTOS though.
I've posted a question on their forum. [1] Let's wait and see if we hear from any real user.

I see one i386 and i686 build farm animals runs Debian.
Perhaps it makes sense to try to reach out to the Debian community,
and see if they know of any PostgreSQL users on 32-bit?

Could we add a text message that is displayed to a user,
when compiling PostgreSQL on a 32-bit platform?
