Modified files:
src/backend/optimizer/plan: planner.c
src/backend/optimizer/util: clauses.c
src/backend/parser: analyze.c parse_agg.c
src/include/optimizer: clauses.h
src/include/parser: parse_agg.h

Log message:
Fix parse_agg.c to detect ungrouped Vars in sub-SELECTs; remove code
that used to do it in planner. That was an ancient kluge that was
never satisfactory; errors should be detected at parse time when possible.
But at the time we didn't have the support mechanism (expression_tree_walker
et al) to make it convenient to do in the parser.
