Amazon Aurora with PostgreSQL Compatibility Supports PostgreSQL 11.4
Following the recent announcement of updates to the PostgreSQL database, we have updated Amazon Aurora with PostgreSQL compatibility to support PostgreSQL version 11.4. PostgreSQL 11 includes major improvements to partitioning, improvements to parallelism, and many other useful performance improvements like adding columns with a non-null column default faster. This version includes SQL stored procedures that allow embedded transactions within a procedure.
