The planner should be able to do better than that, given up-to-date
statistics on the "nodes" column.
Sorry to up this thread, but is there anything I can do to help the
planner in this particular case ?
REINDEXing did not help, nor did ANALYZEing with different STATISTICS
target for this specific column.
