[Feature] Table Partitioning [MySQL 5.1] Yes [PostgreSQL 8.4] via Table Inheritance, Constraint Exclusion, RULES and Triggers - basically RANGE. Issues with using foreign-key constraints with inherited tables in 8.4 the constraint_exclusion has another option called "partition" which is the new default. Which basically means you can have constraint_exclusion for partitioning and not have your other queries suffer. [Microsoft SQL Server 2008] 
Yes - only Enterprise version - functional, range
