+# PostgreSQL Adapter Tests
+
+This directory contains tests for the PostgreSQL adapter with vector extension support.
+
+## Prerequisites
+
+- Docker installed and running
+- Node.js and pnpm installed
+- Bash shell (for Unix/Mac) or Git Bash (for Windows)
+
+## Test Environment
+
+The tests run against a PostgreSQL instance with the `pgvector` extension enabled. We use Docker to ensure a consistent test environment:
+
+- PostgreSQL 16 with pgvector extension
+- Test database: `eliza_test`
+- Port: 5433 (to avoid conflicts with local PostgreSQL)
+- Vector dimensions: 1536 (OpenAI compatible)
+
+## Running Tests
+
+The easiest way to run tests is using the provided script:
+
+```bash
+./run_tests.sh
+```
+
+This script will:
+1. Start the PostgreSQL container with vector extension
+2. Wait for the database to be ready
+3. Run the test suite
+
+## Manual Setup
+
+If you prefer to run tests manually:
+
+1. Start the test database:
+   ```bash
+   docker compose -f docker-compose.test.yml up -d
+   ```
+
+2. Wait for the database to be ready (about 30 seconds)
+
+3. Run tests:
+   ```bash
+   pnpm vitest vector-extension.test.ts
+   ```
+
+## Test Structure
+
+- `vector-extension.test.ts`: Main test suite for vector operations
+- `docker-compose.test.yml`: Docker configuration for test database
+- `run_tests.sh`: Helper script to run tests
+
+## Troubleshooting
+
+1. If tests fail with connection errors:
+   - Check if Docker is running
+   - Verify port 5433 is available
+   - Wait a bit longer for database initialization
+
+2. If vector operations fail:
+   - Check if pgvector extension is properly loaded
+   - Verify schema initialization
+   - Check vector dimensions match (1536 for OpenAI)
+
+## Notes
+
+- Tests automatically clean up after themselves
+- Each test run starts with a fresh database
+- Vector extension is initialized as part of the schema setup
