Re: performance drop on 8.2.4, reverting to 8.1.4

8.1 might have similar problems, but the point here is different: if what
was manually tuned to work in 8.1 confuses the 8.2 planner and performance
drops so much (from 2303 to 231929 ms in my case) upgrading a production
machine to 8.2 is a risky business. I probably have hundreds of sql
statements in my application, some of them quite complex, and it is not
reasonable to check all of them in order to certify them to be 8.2
compliant.
