Why don't you post your SQL statements, table definitions, and estimate
results? I'm sure one or more of the performance experts (Tom Stephan)
could find some improvements. It doesn't makes sense that CREATE TABLE
AS should be faster than INSERT INTO ... SELECT. It should be *slower*
unless you have 2 dozen indexes on the target table.
