-# PostgreSQL Client Library
-
-A comprehensive PostgreSQL client library for the Stock Bot trading platform, designed for operational data, transactions, and relational queries.
-
-## Features
-
-- **Connection Pooling**: Robust connection pool management
-- **Type Safety**: Full TypeScript support with typed queries
-- **Transaction Support**: Multi-statement transactions with rollback
-- **Schema Management**: Database schema validation and migrations
-- **Query Builder**: Fluent query building interface
-- **Health Monitoring**: Connection health monitoring and metrics
-- **Performance Tracking**: Query performance monitoring and optimization
-
-## Usage
-
-```typescript
-import { PostgreSQLClient } from '@stock-bot/postgres-client';
-
-// Initialize client
-const pgClient = new PostgreSQLClient();
-await pgClient.connect();
-
-// Execute a query
-const users = await pgClient.query('SELECT * FROM users WHERE active = $1', [true]);
-
-// Use query builder
-const trades = await pgClient
-  .select('*')
-  .from('trades')
-  .where('symbol', '=', 'AAPL')
-  .orderBy('created_at', 'DESC')
-  .limit(10)
-  .execute();
-
-// Execute in transaction
-await pgClient.transaction(async (tx) => {
-  await tx.query('INSERT INTO trades (...) VALUES (...)', []);
-  await tx.query('UPDATE portfolio SET balance = balance - $1', [amount]);
-});
-```
-
-## Database Schemas
-
-The client provides typed access to the following schemas:
-
-- **trading**: Core trading operations (trades, orders, positions)
-- **strategy**: Strategy definitions and performance
-- **risk**: Risk management and compliance
-- **audit**: Audit trails and logging
-
-## Configuration
-
-Configure using environment variables:
-
-```env
-POSTGRES_HOST=localhost
-POSTGRES_PORT=5432
-POSTGRES_DATABASE=stockbot
-POSTGRES_USERNAME=stockbot
-POSTGRES_PASSWORD=your_password
-```
-
-## Query Builder
-
-The fluent query builder supports:
-
-- SELECT, INSERT, UPDATE, DELETE operations
-- Complex WHERE conditions with AND/OR logic
-- JOINs (INNER, LEFT, RIGHT, FULL)
-- Aggregations (COUNT, SUM, AVG, etc.)
-- Subqueries and CTEs
-- Window functions
-
-## Health Monitoring
-
-The client includes built-in health monitoring:
-
-```typescript
-const health = await pgClient.getHealth();
-console.log(health.status); // 'healthy' | 'degraded' | 'unhealthy'
-```
