  • Performance Improvements: Added memory and timeout management for query processing
  • New Files Added:
    • docker-compose.yml - PostgreSQL container setup
    • init.sql - Database initialization
    • performance_monitor.py - Performance monitoring utilities
    • test_postgres.py - PostgreSQL testing
    • fix_postgres_sequences.py - Sequence management
    • start_postgres.sh / start_postgres.bat - Database startup scripts

Technical Details

  • Renamed database.py to database_postgres.py with enhanced PostgreSQL support
  • Improved query responsiveness through async processing
