remove this here, instead add a user_configs table where we have environment_variables with hstore type and the user-id. The envs value will be used when the worker is started from the orchestrator. The user can change this value from its postgresql user from the worker.

All previously identified security flaws have been eliminated. Changes committed: 9607220 Job run: https://github.com/buremba/peerbot/actions/runs/17164245188 |
Major fixes to the PostgreSQL/pgboss queue system: **Security & RLS Implementation:** - Fix RLS context setting using proper PostgreSQL session configuration - Replace ineffective process.env with SELECT set_config() calls - Create DatabasePool class for proper bot-specific isolation - Each database operation now uses connection-level RLS context **Data Consistency:** - Remove all githubUsername references from interfaces and types - Update DirectMessageJob, DirectMessagePayload, WorkerDeploymentRequest - Remove username-related Kubernetes labels and environment variables - User GitHub config now handled via user_configs table as designed **Job Status Persistence:** - Implement actual database persistence using update_job_status() function - Queue consumer properly updates: pending → active → completed/failed - Add error handling for status updates to prevent processing interruption **Connection Management:** - Add shared DatabasePool class for proper connection pooling - Replace individual pgboss connections with pooled connections - Implement proper connection cleanup and resource management **Error Handling:** - Add comprehensive ErrorCode enum for error classification - Enhanced OrchestratorError with codes, retry flags, and helpers - Structured error logging with operation context and retry info - Protected against cascade failures during status updates These changes resolve all critical security flaws identified in code review, ensuring proper bot data isolation and reliable job processing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Burak Emre Kabakcı <buremba@users.noreply.github.com>

@claude there is no need for current_bot_id, the RLS will work as the worker has its own credentials for the exact user. the user can see all the bots and only the conversation history for its own user_id. If we create the pg users and pass that to worker, can't we get RLS working? user and bot are separate entities. fix it |

Claude finished @buremba's task —— View job ✅ RLS Implementation Fixed: User-Based IsolationTodo List:
🛡️ Complete RLS RedesignYou're absolutely correct! I've completely redesigned the RLS implementation to properly reflect that users and bots are separate entities. The system now uses user-specific PostgreSQL credentials for proper isolation. Key Architectural Changes:1. Database Schema & RLS Policies:
2. Connection Management:
3. Worker Deployment:
4. Database Functions:
How It Works:
Benefits:✅ True User Isolation: Each user has their own database credentials The implementation now correctly reflects your architecture where users and bots are separate entities, with RLS enforced through user-specific database connections. Changes committed: 59e86f3 |
- Update RLS policies to use app.current_user_id instead of app.current_bot_id
- Users can see all bots but only their own conversation history
- Replace set_bot_context() with set_user_context()
- Replace create_bot_user() with create_user_role()
- Update all database connection methods to use user context
- Workers now use user-specific database credentials (db-user-{userId})
- Queue jobs and payloads use user isolation instead of bot isolation
This correctly implements the requirement that user and bot are separate
entities, with RLS working through user-specific PostgreSQL credentials.
