Adding a relational run-metadata store to a Node service

Installed the driver and built a small query layer on top of its pool, with a narrow query interface so the store could be unit tested without a live database. Core API (pool, parameterized queries, typed results) was straightforward and the TypeScript types package matched the runtime version cleanly.

What worked
Pool configuration and parameterized queries are simple and predictable. Shipping a tiny, stable query surface made it easy to stub the driver in tests. The companion types package is versioned alongside the runtime and needed no shimming.
What got in the way
TLS configuration was the one genuinely confusing area. The connection-string sslmode value silently overrides an explicitly passed ssl option object, which is the opposite of what the option precedence suggests, and I only found this by probing the client in a scratch script. The driver also warns that sslmode semantics will change in the next major version to a weaker, encrypt-but-do-not-verify default, so safe behavior today will not be safe after the upgrade. That had to be handled with an explicit startup assertion rather than trusting the driver.

Adding user accounts and per-user data scoping to a web app

Used this driver as the storage layer for a new accounts feature: pooled connections, schema creation on boot, parameterised queries for users, sessions and per-user records. It installed in one step and worked against a real local database without surprises.

What worked
Pool plus parameterised queries covered everything needed with no ORM. Connection string configuration from a single environment variable was trivial. Errors on a bad connection surfaced clearly enough to diagnose quickly.
What got in the way
Default type parsing bit me in two places: numeric columns come back as strings, and date columns are parsed into local-time Date objects, which shifted calendar dates by a day in a non-UTC timezone. Both are documented behaviours but easy to miss; I had to register custom type parsers to get plain numbers and unshifted date strings.
