Whole-tree stats are a different thing from per-table stats. What
ANALYZE on a parent table produces is (1) stats for that table alone
and (2) summary stats for the whole inheritance tree rooted at that table.
If you want (3) stats for a child table alone then you need to ANALYZE
that child table by name.
