RE: _gby_hash_aggregation_enabled=false

Thanks, but in my case, there isn't any specific query that I know of
currently having problems - I just want to disable this feature
proactively since it is known to return the wrong results in some cases.
With most bugs, I don't tend to take proactive action if we haven't
encountered them, however with these "wrong results" bugs I think you
have to take a more proactive approach since you could be encountering
them for a while and not even know it.  In this case, as I understand
it, the results simply come out with missing values from the aggregated
total so, for example - you could have a sales order with ten $100 line
items and instead of totaling $1000, it might come out to something
short of that.  This could go on for a long time before someone noticed
it.  You'd probably have some happy customers, but not such happy
finance folks :-)

I don't remember the name of the hint off hands, but AFAIK there is one
that lets you set the optimizer features enabled per statement.
