MySQL is simpler, faster for read-heavy workloads, and has broader hosting support. PostgreSQL is more feature-rich (JSON, full-text search, custom types, window functions, CTEs), more standards-compliant, and better for complex queries. For web applications: either works well. For data-heavy applications: PostgreSQL. For WordPress and PHP: MySQL. For Supabase, Hasura, or advanced features: PostgreSQL. PostgreSQL has gained significant market share and is now the default choice for new projects in the startup ecosystem.
