I guess what we need to do is hack the emergency-recovery path for error-during-error-processing such that it will prevent trying to print a very long debug_query_string. Maybe we should just not try to print the command at all in this case, or maybe there's some intermediate possibility like only printing the first 1K or so. Thoughts?

I know my 2 cents are not worth that much, but as a DBA, I would really like for you to print at least some of the string causing the abend. This would greatly assist in the tracing of the offending query.
