The post discusses strategies for scaling PostgreSQL, specifically highlighting the use of Citus (a Microsoft subsidiary) and PgDog, which is a Rust-based tool for horizontal scaling, connection pooling, and load balancing. While Citus offers a reliable solution for scaling on platforms like Azure, PgDog presents an alternative approach that potentially allows for more flexible database management without altering application code. Users are also reminded of legacy issues with PostgreSQL, considering its age and the need for evolution in database technology.
