Too Long; Didn't Read

This article discusses the limitations of PostgreSQL's TOAST mechanism for data compression, which was originally designed to manage large values within a PostgreSQL page. While TOAST has its merits, it falls short in terms of optimizing storage efficiency for modern applications with large datasets. The article introduces TimescaleDB's columnar compression functionality as a solution to significantly reduce database size while improving query performance. This approach allows for more efficient storage, making PostgreSQL a more formidable choice for data management in contemporary applications.
