node now does its own grouping of the input rows, and has no need for a
preceding GROUP node in the plan pipeline.  This allows elimination of
the misnamed tuplePerGroup option for GROUP, and actually saves more code
in nodeGroup.c than it costs in nodeAgg.c, as well as being presumably
faster.  Restructure the API of query_planner so that we do not commit to
using a sorted or unsorted plan in query_planner; instead grouping_planner
makes the decision.  (Right now it isn't any smarter than query_planner
was, but that will change as soon as it has the option to select a hash-
based aggregation step.)  Despite all the hackery, no initdb needed since
only in-memory node types changed.

from Andreas.

  - First fixes a problem with a recent patch allowing setNull on updateable
    resultsets
  - Second removed toLower() calls on database object names.  Leave it to
    the caller to correctly pass lower, upper or mixed case.  The driver
    already has methods that the caller can use to determine that postgres
    stores identifiers in lowercase. (unless the identifier was quoted when
    created).

CONVERSION code.  Still need to figure out what to do about inappropriate
coding in parsing.
