May 2026 monthly summary for developer work on opentelemetry-collector-contrib. Focused on improving MySQL query plan visibility in sample data through a new attribute, with testing and documentation upgrades to ensure reliability and adoption.

2026-04 monthly summary for open-telemetry/opentelemetry-collector-contrib. Implemented a robust PostgreSQL null handling improvement in the PostgreSQL receiver data collection path. Fixed warnings/errors caused by null datname and rolename values by skipping datname=null rows and substituting rolename with an empty string to preserve explainability. This is implemented in commit 5ca48dc2a964e400e68f917f59a9bb9df5ad5627 and linked to issues #47768/#47769. Added unit tests to cover the null-handling scenario, ensuring regression safety. Result: reduced log noise, improved reliability of PostgreSQL data collection across instances, and stronger data quality for downstream dashboards and alerts. Demonstrated Go development, query-level testing, and collaborative teamwork (Co-authored-by: Antoine Toulme).
