I'm not extremely familiar with FreeRTOS but my humble understanding
is that it's very different from what we would typically call an
"operating system". If I'm not wrong, basically this is a framework
that adds multitasking to STM32 microcontrollers. This is not exactly
a target hardware for PostgreSQL (although running PostgreSQL on STM32
MCUs could be a fun project for someone looking for a challenging
task.)

What would be actionable items depending on the results? Option A:
someone claims to use PostgreSQL on 32-bit hardware. Option B: no one
admits that they use PostgreSQL on 32-bit hardware (but maybe someone
actually does and/or will in the future). Regardless of the results
you can't drop the support of 32-bit software (until it gets as
difficult and pointless as with AIX that was dropped recently) and it
will not tell you how slow the 32-bit version of PostgreSQL can be.

If there are no actionable items why create a poll?
