I do not believe what you're suggesting can actually work reliably.
In particular it'd fail if we're using our own version of snprintf
and that has different length modifiers than whatever gettext thinks
is the platform standard. Also, how do you think it can possibly work
on platforms lacking the PRId64 macro? gettext would have no better
idea than we do about what to assume that is.
Even if we could trust it to work, it doesn't seem to me that this:
> ereport(ERROR,
> (errcode(ERRCODE_NUMERIC_VALUE_OUT_OF_RANGE),
> errmsg("setval: value %s is out of
> bounds for sequence \"%" PRId64 "\" (%" PRId64 "..%" PRId64
> ")", next, RelationGetRelationName(seqrel), minv, maxv)));
is really any cleaner or easier to read than what we're doing now.
An idea that might be worth considering is to provide a helper function
that converts an int64 to a palloc'd string, so that you could write
errmsg("setval: value %s is out of bounds ...",
int64tostr(next), ...)
If you were executing in a long-lived memory context, this might risk
a memory leak, but we've not had a lot of problems with using other
functions that allocate some memory within ereport calls. In any case
the existing method with a local buffer would work as a fallback
if that were a concern.
