SQLite and PostgreSQL — Both in One Rust Application

Most applications force you to choose: SQLite or PostgreSQL.

This one doesn’t.

One Rust application, two databases, same core logic.

This post explores how a single codebase can switch between SQLite (zero setup) and PostgreSQL (scalable) — without duplication or branching.

• unified connection layer (sqlx::AnyPool)
• runtime database selection
• schema differences
• real-world challenges

No theory-heavy explanations. Just how it actually works.
