Re: 7.4 Press Release -- Draft #3

People,

Remember, everyone, this is a Press Release for the **trade press**.  It does
NOT pay to get too technical.   For example, I'd re-write the below as:

> Improvements to the query planner, including a redesign of subquery
> handling with the IN() clause, resulting in considerable speed
> improvements.

Improvements in subquery handling by the planner resulting in up to 400% speed
increases in some complex queries.

(the 400% is based on a couple of examples on -PERFORMANCE)

Even a trade reporter ... like the Linux Weekly News ... isn't likely to
understand " IN() subquery".

Sure it would, but the from_collapse_order was a big deal to several former
MSSQL DBAs on our lists.

> Are there other databases that use this behavior?

Yes, Sybase.  Not sure about others.  I see where you're going:

Optional explicit join rewriting by the query planner,
allowing an easy transition for MS SQL Server and Sybase
users.

No, it's not.  I point out, though, that MySQL got a significant amount of
press milage out of their support for AIX last year ... even though we've had
it for 2 years.  Since we *do* have production-tested support for Opteron in
this release, we need to trumpet it loud and "grab the high ground."
