We can probably claim that : "Postgres has *low-level* support for table partitioning using and Inheritance, Rules/Triggers and Constraint Exclusion , enabling DBAs to set up complex partitioning schemes" There certainly is much grunt work, but then we can get a better CE performance than just "PARTITION TABLE TTT BY XXX" would give by having constraints on multiple fields in some/all partitions, both overlapping and not, possibly resulting in a better overall system. That is what "low-level" in the above statement means. -- Hannu Krosing
