So you've got some other bug in code you didn't show us. It's highly
unlikely that you wouldn't be able to allocate an 80K buffer. (Whether
that's big enough for your data even yet is a separate question.)
What I was wondering was why you even bothered with the char[] buffer,
when it looked like the actually useful return value was being
accumulated in an expansible StringInfo buffer.
