postgres

Overview ¶

Package postgres links the PostgreSQL driver into a Nucleus application.

Import it for its side effect, once, anywhere in the program:

import _ "github.com/jcsvwinston/nucleus/drivers/postgres"

It registers pgx/v5 under the name "pgx", which is what pkg/db resolves a postgres:// or postgresql:// URL to.

Unlike the other driver modules this one registers no classifier, and that is deliberate rather than an omission: pkg/db reads a PostgreSQL SQLSTATE through the `SQLState() string` method every PostgreSQL driver exposes, so unique-violation detection already works here — for lib/pq too — without naming a driver type.
