This effectively in-lines the CTE expression and results in significant performance improvement. Contrast this to SQL Server syntax. These parameters are important: standby_mode; Specifies whether to start the PostgreSQL server as a standby. When you have more number of keys, You will eventually end-up reading more from disk compared to main memory and Disk access time is very high compared to main memory access time.  We use B-tree indexes to reduce the number of disk accesses. B-tree is a data structure that store data in its node in sorted order.
