n8n Cloud SQL Postgres Node

n8n community node v1.2.1 for Google Cloud SQL PostgreSQL, using the Cloud SQL Connector for authentication. Provides a database node (select, insert, update, upsert, delete, custom query) with batching modes and dynamic schema loading, plus a trigger node for LISTEN/NOTIFY and table row change events. Requires n8n-workflow peer dependency. Intended for self-hosted n8n only (n8n.strict = false, not eligible for n8n Cloud). Release cadence: irregular, open source. Supports IAM and password authentication via Service Account JSON or Application Default Credentials. Key differentiator: direct integration of Cloud SQL Connector for secure auth without IP whitelisting.
