- Add PostgreSQL-specific data types (@db.VarChar, @db.Text, @db.Timestamptz, @db.JsonB, @db.Inet) - Implement comprehensive database constraints via custom migration - Add detailed field-level documentation and enum descriptions - Optimize indexes for common query patterns and company-scoped data - Ensure data integrity with check constraints for positive values and logical time validation - Add partial indexes for performance optimization on failed/pending processing sessions
