PostgreSQL 18 is packing features devs actually want. The big draw? computed and virtual columns, plus privileges views that make security audits easier. This isn’t just hype—it nudges migration planning and security decisions in real time [1].
• computed/virtual columns – Developers wonder if moving logic into the database pays off. The debate note: computed columns can be indexed or even materialized if needed, while VIRTUAL generate columns cannot be indexed, pushing teams to model carefully or shift work to clients [1].
• pggetacl – The developer-facing patch to surface access control details shows how you can surface privilege info more directly, aiding audits and compliance tasks [1].
• pgownerships and pgprivileges – These views would help teams reason about who can do what, a big win for security posture and governance [1].
• Security ergonomics – A lot of data risk hinges on who has access to which data. Rethinking access with these tools can make row- or column-level security more approachable and testable, a theme echoed in developer discussions [1].
Migration takeaway: PostgreSQL 18 nudges teams toward deeper governance baked into the database, but careful planning is still required. Decide where to push logic (DB vs app), whether to rely on new visibility tools, and how indexing constraints affect your data model. The DIY approach remains viable, but these features tilt the balance toward built-in capabilities [1].
Bottom line: PostgreSQL 18 gives new levers for developers and security teams alike; watch how your migration plan leverages privilege views and indexing options in the coming months [1].
