    If there is a primary key column in the GROUP BY clause, every group will have
    only one row. In this case, even if there ungrouped columns in the query, PG 9.2
    doesn't raise any error. But this behaviour is only allowed if the functional
    dependence of the ungrouped columns is not needed to be inferred from subqueries
    (if there are any). In Postres-XC the queries are constructed by creating one
    sub-query for every relation being built in the plan tree. Hence functional
    grouping code is not able to infer the functional grouping in the queries
    constructed by Postres-XC planner at the coordinator. Hence do not ship GROUP BY
    clause when there is functional grouping in the query.
    
    Functional grouping also means that there is one row per group, thus grouping at
    the datanode is not expected to improve performance (may decrease it).

    Support statement triggers with COPY.
    Add restriction: Non-shippable ROW triggers not supported with COPY.
    In triggers.sql, added a ';' after the COPY stdin data so as to prevent
    further statements from failing.
    Added triggers_1.out to accommodate the "ROW triggers with COPY not supported"
    message so as to make triggers.sql pass.
