I need some help. I was looking at this e-mail (http://archives.postgresql.org/pgsql-performance/2005-06/msg00369.php), and it gave me a good idea on how to fake partitioning. I have created a test database with serveral identical tables. Table_2003, Table_2004, Table_2005, etc I then created the view "test_view" and defined as a union all of all of the tables. I have created several do instead insert rules trying to force the data into the correct table when I load from production data into the view/tables. However, PostgreSQL will not preform the inserts when trying to load the data. It complains about needing an uncondition ON INSERT DO INSTEAD rule. Is there anyway to have a rule that would correctly insert the data from the view into the correct underlying table when loading a file with several years of data? Thanks, Chris
