Pivotal Greenplum 6 incorporates several new features from PostgreSQL versions 8.4 through version 9.4. INTERVAL Data Type Handling PostgreSQL 8.4 improves the parsing of INTERVAL literals to align with Planner support for ordered-set aggregates and moving-aggregates (PostgreSQL 9.4). Support for jsonb data type (PostgreSQL 9.4). DELETE, INSERT, and UPDATE supports the WITH clause, CTE (common table expression) table to support ordered-set aggregates and moving-aggregates with the Postgres Planner (PostgreSQL 9.4). The ALTER/CREATE/DROP AGGREGATE SQL command signatures have also been updated to reflect the pg_aggregate
