These are bad processors born out of ridiculous market segmentation done by Intel for which we pay for dearly (also worth calling out making ECC server-only feature, because profit, exabytes of user data corrupted be damned).
Not only they are not worth targeting, it is a moral imperative not to consider them for pieces of software like PostgreSQL. If the push comes to shove, a "-compat" or "-legacy" flavour of binaries can be offered to select few users which use older systems with CPUs made before 2011 (pre-Sandy-Bride and Jaguar respectively), which would allow the overall ecosystem get healthier while not leaving affected people behind.
The Atom-based processors are bad not because of market segmentation but because Intel is perennially unable to make more than one good architecture at a time. The ones that are bad because of market segmentation are the processors with a Core family microarchitecture lobotomized down to the i3, Pentium or Celeron product lines, leaving them years behind on feature support that's physically present but fused off.
