PostgreSQL is the most advanced open-source database in terms of SQL processing capabilities. However, many users are unaware of the sheer power hiding inside its SQL engine and still write SQL-92 statements. With advanced SQL capabilities, much higher concurrency and performance can be achieved. This talk discusses some of the modern SQL techniques for developing applications with examples. • Implementation of data retention policy (archiving and purging) as a single statement. • Partitioning large tables without causing heavy wait locks or downtime. • Advanced uses of CTE - Complex transactions as a single statement. • Modern features like Merge and its use, such as replacing pl/pgsql procedures with single statements. • Cost of rollbacks and method to avoid
