Similar is 32/64 bit compilation. It is handled on x86 by MAXALIGN but MAXALIGN is same on SPARC for both binaries, but I'm not sure if it works correctly.

Are 32/64-bit binaries on Sparc incompatible, then? Does our control file check catch it? If not, what's causing it, and would the --footprint switch catch it?


It is what I don't know. controlfile only says "incorrect checksum in control file". It seems to me that CRC computing does not work correctly. I check pg_control footprint and it is same for 32/64. It seems to me a false positive complain, but ...

Footprint switch should help show you why it is incompatible and also protect you during development to break some structure.
