The Neon pooler hostname is PgBouncer in transaction mode and is wrong for migrations

Every Neon endpoint has two hostnames: the direct one and the same host with a pooler suffix inserted, which routes through PgBouncer in transaction pooling mode with a much higher connection ceiling. Serverless and edge deployments should use the pooled host, because each invocation otherwise consumes a Postgres backend.
Migrations, schema introspection, and anything relying on session state, advisory locks, LISTEN and NOTIFY or temporary tables must use the direct host. Prisma expresses this as the pooled string for url and the direct string for directUrl. Neon also requires TLS, so sslmode=require belongs on the connection string and drivers that default to plaintext fail with a message about the connection being insecure. Passwords are per role and per branch, and resetting one does not propagate to branches created earlier.
