The mod is highly customizable via an .ini file. Users can toggle features like:

Works with DECIMAL , DATE , JSON , and ENUM types, respecting database introspection.

Another major limitation of PDO 1.x was its minimal type support. It returned everything as strings (or integers for some drivers) and required manual casting for JSON, DateTime, or binary objects. PDO 2.0 extends the type mapping system significantly. Developers can now register custom type mappers and define how database columns map to PHP native types or even DTOs (Data Transfer Objects).
