I think any solution that involves adding more duplication at each
strtol() callsite is not great ("Don't Repeat Yourself"). I'd still like
to see this refactored into a separate function, as I suggested on
-patches. If people would like to see a detailed explanation of the
interaction between strtol() and errno, a header comment to pg_strtol()
seems a good place to put it. IMO that is better than copying and
pasting a cryptic one-line comment to each and every callsite of
strtol().
