Umair Shahid continues a series on migrating from Oracle to Postgres:
When moving from Oracle to PostgreSQL, one of the key differences lies in how each database handles roles and privileges. Oracle’s privilege model is deeply ingrained in enterprise systems, with fine-grained user controls and a strict distinction between users and roles. PostgreSQL, while just as capable, approaches roles and privileges differently, offering flexibility and simplicity, but it also requires a shift in mindset for Oracle users.
This article provides a practical guide for Oracle experts to understand and implement roles and privileges in PostgreSQL, addressing the structural differences, common challenges, and best practices to make this transition smooth.
Read on for the differences between the two platforms.
