This is the list I'm working off of for the "What's New in 8.3"
lightning talk at OSCon. I'm going to kind-of lump all the
performance stuff together (and most of that is going to get a very,
very quick overview), and blitz through the improved statistics stuff
in like 10 seconds... everything else I'm going to essentially go
through in the order shown here, and whatever I can fit in in the
time remaining is what makes it in. So, two questions...
1) Am I missing anything? (I'm not going to mention anything that
hasn't been committed unless it's *really* big; namely HOT and tsearch)
2) Any *serious* issues with the ordering?
Keep in mind that this is 100% targeted at *end users*, so these need
to be ranked on how much they'll affect them. There's tons of patches
that haven't even made this list not because they're not important,
but because they just won't have that big of a direct impact on end
users. Performance stuff sort of falls into this category... people
care a lot about how performance has improved, but far less about how
it was actually done (plus 5 minutes is nowhere near enough to do any
justice to most of the performance stuff).
