Features I Wish MySQL Had but Postgres Already Has

- #Database Comparison
- #PostgreSQL
- #MySQL
- PostgreSQL supports transactional DDL, allowing schema changes to be rolled back, unlike MySQL where DDL statements auto-commit.
- PostgreSQL allows creation of custom data types and domains for better data modeling and type safety, whereas MySQL's ENUM support is limited.
- PostgreSQL has native array support for storing and querying lists of values, simplifying data models without requiring separate tables.
- PostgreSQL's Common Table Expressions (CTEs) are more mature and feature-complete compared to MySQL's basic CTE support.
- PostgreSQL offers Row Level Security (RLS) for fine-grained access control at the database level, which MySQL lacks.
- PostgreSQL supports partial indexes with WHERE clauses, making them more efficient for specific query patterns, unlike MySQL which requires full column indexing.
- PostgreSQL's PostGIS extension provides superior geospatial capabilities compared to MySQL's spatial support.
- PostgreSQL's pgvector extension offers advanced vector storage and similarity search, more mature than MySQL's recent vector support.
- PostgreSQL adheres closely to SQL standards with better error messages and predictable behavior, while MySQL's parser is more lenient.
- PostgreSQL has a permissive license and open community, contrasting with MySQL's restrictive dual-licensing model and opaque development process.
