Session Goal

The session aimed to resolve Dockerized PostgreSQL connection issues and optimize data handling.

Key Activities

• Port Conflict Resolution: Explored solutions for port conflicts when running Dockerized Postgres, including changing host ports and stopping conflicting services.
• Database Connection: Established connections to PostgreSQL using pggmail, with instructions for psql commands and Python operations.
• SSL Mode Fixes: Addressed SSL mode errors in Docker Postgres connections using psycopg2 and performed sanity checks.
• JSON Handling Improvements: Enhanced JSON loader for PostgreSQL with SSL support, faster NUL handling, and configurable sanitization.
• NUL Character Handling: Implemented solutions for handling escaped NULs in JSONB data during PostgreSQL loading.

Achievements

• Successfully resolved Docker Postgres port conflicts and SSL mode issues.
• Improved JSON data handling and performance in PostgreSQL loaders.

Pending Tasks

• Further testing and validation of the implemented solutions in a production environment to ensure stability and performance.
