Update of /home/projects/pgsql/cvsroot/pgsql/src/include/nodes
from hub.org:/home/projects/pgsql/tmp/cvs-serv25842/src/include/nodes
Modified Files:
primnodes.h
----------------------------- Log Message -----------------------------
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...
