- Author created a QR-code generator for PostgreSQL using a single pure SQL statement.
- The generator doesn't require external libraries or Postgres extensions.
- Two versions are available: basic (pqr.sql) and a safer version (pqrsafe.sql) that checks payload length.
- PostgreSQL 17 showed better performance than version 16 in initial tests.
- The project was completed in an hour using OpenAI Codex, contrasting with a manual utility written 20 years ago.
