Operations and configuration can vary by connector version. Check the full PostgreSQL guide.
An app you could build
Show stock by SKU and warehouse, filter items that need attention, and let authorized staff submit quantity changes through a form.
I have an inventory table in PostgreSQL with SKU, warehouse, quantity, and reorder level columns. Build an inventory dashboard with warehouse filters and a low-stock view. Let an operator inspect an item and confirm a quantity update before saving it.

Watch a PostgreSQL-backed vendor risk register take shape with create, read, update, and delete operations, validation, search, filters, and role-based access.
The video uses ToolJet MCP. Use the prompt alongside it to start a similar app in ToolJet’s AI builder, then configure your connections and permissions.
I have vendors, risk scores, and findings in PostgreSQL tables. Build a vendor risk register with search, filters, pagination, and validated forms for creating and updating records. Give Procurement access to vendor records, Security access to risk scores and findings, and Compliance Admins full access, with confirmation before deleting records.

Questions, answered
Build internal apps that query and update PostgreSQL data with SQL or supported GUI operations. Supported capabilities: Run SQL queries; List and create rows; Update and delete rows; Bulk insert and upsert.
A reachable PostgreSQL host, database name, and database credentials, or a connection string. Configure SSL and SSH options to match your deployment.
Use a database role with only the required privileges. Parameterize queries and enforce row restrictions in server-side queries; hiding a table column is not access control.
Connect PostgreSQL queries to app events such as button clicks and form submissions. ToolJet Workflows and Agent Builder can orchestrate supported connectors on Self-hosted deployments; those products are not available on ToolJet Cloud. Check the connector and deployment requirements for your use case.
