Hmm. I tried this out. typedef Datum to be long long int on a 32-bit
platform and compile. You get lots of warnings, but none about a format
problem. But if you explicitly insert a call like elog(INFO "datum is %lu",
somedatum), then you see a warning. So this problem might not be very
widespread.

Possibly, or everyone was too confused and didn't know where to start.
I think this proposed change is a step in the right direction, and it doesn't
make things worse for anyone else.
