Support for TypedDict with row_factory in psqlpy

[akanksha314e]

Currently, psqlpy supports using the row_factory method for mapping results to Python objects like Pydantic models. However, it does not support mapping to TypedDict, which is a common construct used for type-safe dictionary-like objects in Python.
Steps to reproduce:

1. Create a TypedDict class:
   from typing import TypedDict

class MyTypedDict(TypedDict):
id: int
name: str
2. Use the row_factory to map results to this TypedDict:
def to_class(class_):
def to_class_inner(row):
return class_(**row)
return to_class_inner

conn_result.row_factory(row_factory=to_class(MyTypedDict))
the code raises a TypeError.

@akanksha314e Hello!

Thank you for the issue. Could you please specify the database table schema, SQL query, and PSQLPy code?

@akanksha314e In general, you don't need to use row_factory functionality, just use as_class method on result:

class MyTypedDict(TypedDict):
	id: int
	name: str


typed_result = conn_result.as_class(MyTypedDict)
