I think partial is the right terminology. Unlike a parallel sequential scan, a partial aggregate isn't parallel-aware and could be used in contexts having nothing to do with parallelism. It's just that it outputs transition values instead of a finalized value. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
