If you're using the Approvals feature, there can also be entries with 
type approval in the table. This is already possible right now, so the 
test can not be removed.

Can you optimize the query in a way, that the test is only done later, 
like on the result of the query without that condition? However, even if 
you find a solution, I'm not sure, RT's query can be changed to match 
that. IMHO it's a serious flaw in Oracle's query optimizer that adding a 
condition that's always true significantly slows down a query.
