I remember the first backtrace a made for this was on the line of the
elog but then a second backtrace was with the function, now that
repeat it with line of the function for the elog (and the original
query) i see again create_incrementalsort_plan() which made me try
with enable_incremental_sort disabled...
sorry for that, attached a better backtrace
