Subject: Revise aggregate functions per earlier discussions in pghackers.
 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...
