bec98a31c5 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...

f2d1205322 Another batch of fmgr updates. I think I have gotten all old-style
functions that take pass-by-value datatypes.  Should be ready for
port testing ...

3cb8c8da68 Clean up problems with rounding/overflow code in NUMERIC, particularly
the case wherein zero was rejected for a field like NUMERIC(4,4).
Miscellaneous other code beautification efforts.

b5626a2089 Restricted maximum precision for NUMERIC to 1000 digits.
Anything else is CPU overkill.

exponents.
