Thanks for your comments.
I overlooked the check for MCV in the logic building query
because I created the patch as a new feature on PG14.
I'm not sure whether we should do back patch or not. However, I'll
add the check on the next patch because it is useful if you decide to
do the back patch on PG10, 11, 12, and 13.
I wonder the column names added by \dX+ is fine? For example,
"Ndistinct_size" and "Dependencies_size". It looks like long names,
but acceptable?

Tatsuro Yamada
