Here is the pg_stats data. The explain analyze queries are still running.

select * from pg_stats where tablename = 'f_pageviews' and attname = 'date_key';
schemaname | tablename | attname | null_frac | avg_width | n_distinct | most_common_vals | most_common_freqs | histogram_bounds | correlation
------------+-------------+----------+-----------+-----------+------------+-------------------------------------------+---------------------------------------------------------------------------------------------------+-----------------------------------------------+-------------

Please show EXPLAIN ANALYZE output for your queries, not just EXPLAIN.
Also it would be useful to see the pg_stats rows for the date_key and
