extensions to support our historical behavior. An aggregate belongs to the closest query level of any of the variables in its argument, or the current query level if there are no variables (e.g., COUNT(*)). The implementation involves adding an agglevelsup field to Aggref, and treating outer aggregates like outer variables at planning time.

some of the algorithms for higher functions. I see about a factor of ten speedup on the 'numeric' regression test, but it's unlikely that that test is representative of real-world applications. initdb forced due to change of on-disk representation for NUMERIC.

parameter to allow it to be forced off for comparison purposes. Add ORDER BY clauses to a bunch of regression test queries that will otherwise produce randomly-ordered output in the new regime.

so that precision of result is always at least as good as you'd get from float8 arithmetic (ie, always at least 16 digits of accuracy). Per pg_hackers discussion a few days ago.

There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...

which is broken in some weird way that I don't understand. I think it may be exposing a bug in the new psql --- for one thing, I get different results when I run psql by hand than the regress script gets. What the heck???

Note this forces initdb because of change of Aggref node in stored rules.
