Apparently we need to be more explicit. What we want to see is
select most_common_vals from pg_stats
where tablename = 'child' and attname = 'id';
select most_common_vals from pg_stats
where tablename = 'core' and attname = 'groupid';
from both databases. (Adjust as necessary if those weren't the
real table and column names.) We probably don't need the specific
array elements, but we do want to know how big those arrays are.
