Hm. Something like 'Currently the maximum length of a StringInfo is
1GB.'? I don't really think it's worth pointing out that they may not be
consistent, when they currently are...
And I suspect we should just fix the length limit to be higher for both,
perhaps somehow allowing to limit the length for the backend cases where
we want to error out if a string gets too long (possibly adding a
separate initialization API that allows to specify the memory allocation
flags or such).

Indeed.
Thanks for looking,
