It would appear that something is wrong with check_stack_depth(),
and/or getrlimit(RLIMIT_STACK) is lying to us about the available stack.
None of that logic has changed in awhile. You might try checking what
the max_stack_depth GUC gets set to by default in each build, and how that
compares to what "ulimit -s" has to say. If it looks sane, try tracing
through check_stack_depth.
