MySQL has a table max row size limit of 65,535 bytes.

PostgreSQL has a table max row size limit of 10M bytes.

• translates to 10 MB per row.

PostgreSQL

It gives more flexibility in data types, scalability, concurrency, and data integrity.

• supports other additional data types like arrays and XML.
