Note

Adds a compatibility matrix showing PostgreSQL database support across different environments (self-hosted, Azure, AWS Aurora, AWS RDS). The table currently only includes PostgreSQL entries and is missing corresponding MySQL entries despite MySQL being mentioned throughout the documentation.

Issues Found

The database compatibility matrix has 3 issues that should be addressed:

1. Missing MySQL entries: The table only includes PostgreSQL but the documentation extensively mentions MySQL compatibility
2. Empty tested version cells: Several rows have blank "Tested versions" columns that should be filled or marked as "N/A"
3. Incomplete coverage: The matrix should reflect all database types mentioned in the text for consistency

See inline comments for specific line suggestions.
