Hi guys
Im running a Datawarehouse benchmark (APB-1) on PostgreSql. The objective is to
choose which of the to main db (PostgreSQL, MySQL) is fastest. I've run into a
small problem which I hope could be resolved here.

select count(*)
The TPC-H/R rules allow only minor changes to the SQL that are necessary
due to SQL implementation differences. They do not allow changes made to
improve performance. It is their way to test optimizer's ability to
recognize an inefficient SQL statement and do the rewrite.
The rule makes sense
