- Oracle introduced support for the Boolean data type in release 23ai, addressing a long-standing limitation.
- Previously, developers used workarounds like VARCHAR2/NUMBER to simulate Boolean values, impacting performance and storage efficiency.
- PostgreSQL has supported Boolean data natively for over two decades, offering efficient storage and simpler queries.
- Workarounds in Oracle included using CHAR(1) or NUMBER(1) with checks, leading to redundant conversions and conditions.
- PostgreSQL allows direct logical operations with Boolean values, resulting in cleaner and more performant queries.
- A comparison table highlights the advantages of Boolean over CHAR(1) and NUMBER(1) in terms of storage, type safety, and readability.
- HexaRocket, a migration tool, can automatically map Oracle's CHAR(1)/NUMBER(1) to PostgreSQL's Boolean during database migration.
- The article promotes HexaRocket for seamless migration from Oracle or SQL Server to PostgreSQL.
