Okay, actually I did not understand the clear logic of when to use
%llu and to use (U)INT64_FORMAT. They are both used for 64-bit
integers. So do you think it is fine to replace all INT64_FORMAT in
my patch with %llu?

Okay, so you mean irrespective of this patch should this be converted
to ereport?
