hamster died a couple of years ago, it was a RPI1 and I have not
bought one after. RIP to it. I still have dangomushi, a RPI2, based
on armv7l and that's 32-bit. Heikki has chipmunk, which is a RPI1
last time we discussed about that. The good thing about those
machines is that they are low-energy consumers, and silent. So it is
easy to forget about them and just let them be.

Those 32-bit modules are still being sold actively by the RPI
foundation, and used as cheap machines for education purposes, so I
think that it is still useful for Postgres to have active buildfarm
members for 32-bit architectures.
