Ignore parallel workers in pg_stat_statements Oversight in 4f0b0966c8 which exposed queryid in parallel workers. Counters are aggregated by the main backend process so parallel workers would report duplicated activity, and could also report activity for the wrong entry as they are only aware of the top level queryid. Fix thinko in pg_stat_get_activity when retrieving the queryid. Remove unnecessary call to pgstat_report_queryid().
