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.
