Re: [PATCH] Planner support function for generate_subscripts()

[shihao zhong]

Hi Andrew,

Thanks for testing and for the review. You're right. From statistics,
estimate_array_length() counts only distinct non-null elements, so the
estimate can also be too low.

v5 rewords that comment.

Thanks,
Shihao
