Truss ships with 33 curated PostgreSQL extensions that you can enable or disable from the dashboard. Extensions add data types, indexing strategies, search capabilities, and more to your database.
Navigate to Database → Extensions in the dashboard to see all available extensions. Each extension shows:
- Name and description
- Category (Search, Data Types, Indexing, Security, Utilities, Performance, Geospatial, Federation, Diagnostics)
- Version available
- Toggle switch to enable/disable
Click the toggle switch to enable. This runs CREATE EXTENSION IF NOT EXISTS <name> on your database.
Click the toggle to disable. If other database objects (tables, functions, indexes) depend on the extension, you’ll be prompted to confirm a CASCADE drop.
