+
+# Komga logs
+docker-compose logs komga
+
+# All logs
+docker-compose logs -f
+```
+
+### 6. Access PostgreSQL:

+# Connect via psql
+docker-compose exec postgres psql -U komga -d komga
+
+# Connect from host
+psql -h localhost -p 5433 -U komga -d komga
+```
+
+## Scripts
+
+### run-local-with-postgres.sh
+```bash
+#!/bin/bash
+# Script to run Komga locally with PostgreSQL
+
+set -e
+
+echo "Starting PostgreSQL container..."
+docker-compose up -d postgres
+
+echo "Waiting for PostgreSQL to be ready..."
+sleep 5
+
+echo "Building Komga..."
+./gradlew :komga:build -x test
+
+echo "Running Komga with PostgreSQL..."
+SPRING_PROFILES_ACTIVE=docker \
+KOMGA_DATABASE_TYPE=postgresql \
+KOMGA_DATABASE_URL="jdbc:postgresql://localhost:5433/komga" \
+KOMGA_DATABASE_USERNAME=komga \
+KOMGA_DATABASE_PASSWORD=komga123 \
+KOMGA_CONFIG_DIR="$HOME/.komga-postgres" \
+./gradlew :komga:bootRun
+
+echo "Komga is running at http://localhost:25600"
+echo "PostgreSQL is running at localhost:5433"
+echo "To stop: docker-compose down"
+```
+
+### run-test-with-docker.sh
+```bash
+#!/bin/bash
+# Script to run Komga tests with PostgreSQL using Docker Compose
+
+set -e
+
+echo "Starting PostgreSQL test container..."
+docker-compose -f docker-compose-test.yml up -d postgres-test
+
+echo "Waiting for PostgreSQL to be ready..."
+sleep 10
+
+echo "Building Komga..."
+./gradlew :komga:build -x test
+
+echo "Running tests with PostgreSQL..."
+./gradlew :komga:test --tests "*PostgreSQL*" --info
+
+echo "Running integration tests..."
+./gradlew :komga:integrationTest --info
+
+echo "Stopping test containers..."
+docker-compose -f docker-compose-test.yml down
+
+echo "Test completed!"
+```
+
+## Port Configuration
+
+### Default Ports:
+- **PostgreSQL**: 5433 (host) → 5432 (container)
+- **Komga API**: 25600 (host) → 25600 (container)
+
+### Change Ports:
+Để thay đổi ports, sửa file `docker-compose.yml`:
+```yaml
+services:
+  postgres:
+    ports:
+      - "NEW_PORT:5432"  # Thay NEW_PORT bằng port mong muốn
+  
+  komga:
+    ports:
+      - "NEW_PORT:25600"  # Thay NEW_PORT bằng port mong muốn
+```
+
+## Volume Persistence
+
+### PostgreSQL Data:
+- Volume: `postgres_data`
+- Location: `/var/lib/postgresql/data` (container)
+- Persists: Database data, tables, indexes
+
+### Komga Configuration:
+- Volume: `komga_config`
+- Location: `/config` (container)
+- Contains: Application configuration, logs, Lucene indexes
+
+### Host Mounts:
+- `./data:/data:ro`: Read-only comic/manga library directory
+- `./docker/postgres/init.sql:/docker-entrypoint-initdb.d/init.sql`: Init script
+
+## Health Checks
+
+### PostgreSQL Health Check:
+```yaml
+healthcheck:
+  test: ["CMD-SHELL", "pg_isready -U komga"]
+  interval: 10s
+  timeout: 5s
+  retries: 5
+```
+
+### Dependency Management:
+Komga service sẽ đợi PostgreSQL healthy trước khi start:
+```yaml
+depends_on:
+  postgres:
+    condition: service_healthy
+```
+
+## Troubleshooting
+
+### 1. Port Already in Use:
+```bash
+# Check what's using port 5433
+lsof -i :5433
+
+# Kill process using port
+kill -9 $(lsof -t -i:5433)
+```
+
+### 2. PostgreSQL Connection Issues:
+```bash
+# Check PostgreSQL logs
+docker-compose logs postgres
+
+# Test connection
+docker-compose exec postgres pg_isready -U komga
+```
+
+### 3. Reset Database:
+```bash
+# Stop and remove volumes
+docker-compose down -v
+
+# Start fresh
+docker-compose up -d
+```
+
+### 4. Backup Database:
+```bash
+# Backup to file
+docker-compose exec postgres pg_dump -U komga komga > backup.sql
+
+# Restore from file
+cat backup.sql | docker-compose exec -T postgres psql -U komga -d komga
+```
+
+## Development Notes
+
+### 1. Local Development vs Docker:
+- **Local**: Chạy backend với `./gradlew :komga:bootRun`, PostgreSQL trong Docker
+- **Docker**: Chạy cả backend và PostgreSQL trong Docker
+
+### 2. Test Configuration:
+- Test containers sử dụng `docker-compose-test.yml`
+- Database name: `komga_test`
+- User: `postgres` (default PostgreSQL user)
+
+### 3. Extensions Required:
+- `uuid-ossp`: UUID generation
+- `pg_trgm`: Text search and pattern matching
+- `unaccent`: Accent removal (thay thế UDF_STRIP_ACCENTS)
+
+### 4. Performance Considerations:
+- Adjust `shared_buffers` và `work_mem` trong production
+- Consider connection pooling với PgBouncer
+- Monitor với `pg_stat_statements` extension

+# PostgreSQL Migration - Sprint 1 Summary
+
+## Mục tiêu
+Implement PostgreSQL database support cho Komga while maintaining backward compatibility với SQLite.
+
+## Kiến trúc đã triển khai
+
+### 1. Database Abstraction Layer
+- **DatabaseType enum**: `SQLITE`, `POSTGRESQL`
+- **DatabaseUdfProvider interface**: Abstract UDF/collation functions
+  - `SqliteUdfProvider`: SQLite implementation (REGEXP, UDF_STRIP_ACCENTS, COLLATION_UNICODE_3)
+  - `PostgresUdfProvider`: PostgreSQL implementation (pg_trgm, unaccent extension)
+- **JooqUdfHelper**: Spring component cung cấp database-agnostic extension methods
+
+### 2. Cấu hình DataSource
+- **DataSourcesConfiguration**: Tạo DataSource dựa trên database type
+- **Dynamic JOOQ dialect**: `KomgaJooqConfiguration` sử dụng `SQLDialect` động
+- **Flyway vendor detection**: Tự động sử dụng `{vendor}` directory (sqlite/postgresql)
+
+### 3. Migration Strategy
+- **Two-phase bean registration**: Sprint 1 tập trung infrastructure, UDF implementations có thể stub
+- **Backward compatibility**: SQLite vẫn là default
+- **Tasks database**: Giữ nguyên SQLite cho tasks database (đơn giản hóa Sprint 1)
+
+## Các file đã tạo/sửa

+- `run-test-with-docker.sh`: Chạy tests với Testcontainers PostgreSQL
+- `test-postgresql.sh`: Script test tổng quát
+
+## Testing
+
+### Integration Test:
+```kotlin
+@Testcontainers
+@SpringBootTest
+@ActiveProfiles("test")
+class PostgreSQLIntegrationTest {
+    @Container
+    val postgres = PostgreSQLContainer("postgres:16-alpine")
+    
+    @Test
+    fun `should connect to PostgreSQL database`() {
+        // Test database connection
+    }
+    
+    @Test  
+    fun `should use PostgreSQL UDF provider`() {
+        // Test UDF provider selection
+    }
+}
+```
+
+## UDF/Collation Mapping
+
+### SQLite → PostgreSQL:
+- `REGEXP` → PostgreSQL regex operators (`~`, `~*`)
+- `UDF_STRIP_ACCENTS` → `unaccent()` function
+- `COLLATION_UNICODE_3` → `COLLATE "C"` hoặc custom collation
+
+### JooqUdfHelper methods:
+```kotlin
+class JooqUdfHelper(
+    private val databaseUdfProvider: DatabaseUdfProvider
+) {
+    fun <T> Field<T>.collateUnicode3(): Field<T> = 
+        databaseUdfProvider.collateUnicode3(this)
+    
+    fun Field<String>.stripAccents(): Field<String> =
+        databaseUdfProvider.stripAccents(this)
+    
+    fun Field<String>.likeRegex(pattern: String): Condition =
+        databaseUdfProvider.likeRegex(this, pattern)
+}
+```
+
+## Các bước tiếp theo (Sprint 2)
+
+1. **Complete UDF implementations**: Hoàn thiện `PostgresUdfProvider` implementations
+2. **JOOQ code generation**: Tạo JOOQ code cho PostgreSQL schema
+3. **Comprehensive testing**: Test tất cả API endpoints với PostgreSQL
+4. **Performance optimization**: Tối ưu queries cho PostgreSQL
+5. **Documentation**: Hướng dẫn migration từ SQLite sang PostgreSQL
+
+## Status hiện tại
+✅ **Build thành công** với SQLite  
+✅ **Backend khởi động** và chạy Flyway migrations  
+✅ **PostgreSQL infrastructure** đã sẵn sàng  
+✅ **Docker setup** hoàn chỉnh  
+⏳ **Integration tests** cần chạy với Testcontainers
+
+## Lưu ý quan trọng
+- **Backward compatibility**: SQLite vẫn là default database
+- **Tasks database**: Vẫn dùng SQLite cho đơn giản
+- **Flyway**: Tự động detect vendor và sử dụng migration directory phù hợp
+- **JOOQ**: Runtime dialect dynamic, code generation vẫn dùng SQLite (Sprint 2 sẽ update)
