Uh, which? We have some that are affected by configure flags, but otherwise we should be endianess & alignment independent. And *even if* that were the case, that's not a good reason to continue a bad practice. > For jsonb we decided to implement a version flag within the type > itself, which I thought mistake at the time -- better to have a > version header in the COPY BINARY if needed. What's the problem with the version? How does a COPY BINARY flag address normal clients? Greetings, Andres Freund
