Why do I feel that you are using my design? Probably because you are solving
same problem as I am solving..:-)

In postgresql, you can inherit a table from another table. You can query on
base table and gather rows from child table. So make an empty base table, make
each hourly table child of base table and query on base table. It will take
care of everything. Remove the hourly table after 48 hours..
