PostgreSQL
Relational
The default choice for a new business system. Strict data types, real transactions, complex reporting queries, and JSON columns when part of the data genuinely has no fixed shape.
We use it for: ERP, booking and accounting systems, and anything where a wrong number is worse than a slow page.
Wrong choice when: An application you did not write hard-codes MySQL syntax, or your hosting genuinely offers nothing else.
