Here is a neutral and interesting 1-paragraph summary of the provided text: PostgreSQL's partitioning and LockManager limitations can lead to scalability issues, particularly when querying large tables with many partitions. In contrast, YugabyteDB offers distributed tables, indexes, and linear scalability, making it an attractive option for scaling PostgreSQL applications without changing the application code. By leveraging automatic sharding or YSQL declarative partitioning, developers can simplify operations and improve execution performance, while avoiding the limitations of PostgreSQL's lock manager contention.
