Perhaps we should reconsider our general position on hints then and
add them so users can define the plan to be used.. For my part, I don't
see this as all that much different.
Consider if we were just adding HashJoin support today as an example.
Would we be happy if we had to default to enable_hashjoin = off? Or if
users had to do that regularly because our costing was horrid? It's bad
enough that we have to resort to those tweaks today in rare cases.
Thanks,
Stephen
