• Robust data types including JSON/JSONB
• Advanced indexing capabilities
• Excellent scalability and performance
• Built-in replication support
• Rich ecosystem of extensions

Getting Started

Connection Setup

const { Pool } = require('pg')

const pool = new Pool({
  user: process.env.POSTGRES_USER,
  host: process.env.POSTGRES_HOST,
  database: process.env.POSTGRES_DB,
  password: process.env.POSTGRES_PASSWORD,
  port: process.env.POSTGRES_PORT
})

Basic Operations

// Query example
const result = await pool.query(
  'SELECT * FROM users WHERE active = $1',
  [true]
)

// Insert example
await pool.query(
  'INSERT INTO users(name, email) VALUES($1, $2)',
  ['John Doe', '[email protected]']
)

Neon Integration

Neon provides serverless PostgreSQL with automatic scaling and branching capabilities:

1. Sign up at neon.tech
2. Create a new project
3. Get connection string
4. Use with any PostgreSQL client

Best Practices

• Use connection pooling for better performance
• Implement proper error handling
• Use parameterized queries to prevent SQL injection
• Set appropriate timeout values
• Implement retry logic for transient failures
