Can we check if AWS supports Postgres version 18? IIRC, v18 has built in UUIDv7 function.

Question: Since we don't have any queries yet, can we defer the initialisation of pgx until we have our first query?

Can explore go tool to setup sqlc and atlas. I think we can pin the tools to specific version and contributors no need to manually install tools.

🚀 Summary
Wire pgx/v5 into the server as the PostgreSQL driver, with sqlc and Atlas configured for type-safe queries and schema migrations. The pool is initialised in run() at startup,
pinged to fail fast on an unreachable database, and injected into the handler. No queries or schema tables are added yet — this is purely the wiring and tooling foundation.
