Invalid OID Handling in SQLAlchemy with asyncpg and autoload_with Causes DataError

Describe the bug

I encountered an issue when using SQLAlchemy with asyncpg and the autoload_with option while trying to load table metadata. The problem occurs because PostgreSQL's oid type is treated as a signed 32-bit integer (int32) by asyncpg, which leads to a DataError when the OID value exceeds the maximum range of int32 (2,147,483,647).

Steps to Reproduce

1. Create a PostgreSQL table with an OID that exceeds the int32 range. For example, an OID like 3195477613.
2. Use SQLAlchemy to define the table with autoload_with to load metadata:

from sqlalchemy import Table, MetaData

metadata = MetaData()
table = Table("master_product_view", metadata, autoload_with=conn)

3. Execute the code.

Observed Behavior

The following exception is raised during metadata loading:

sqlalchemy.exc.DBAPIError: (sqlalchemy.dialects.postgresql.asyncpg.Error) <class 'asyncpg.exceptions.DataError'>: invalid input for query argument $1: 3195477613 (value out of int32 range)

Expected Behavior

The autoload_with option should correctly handle OID values, even if they exceed the int32 range.

asyncpg/SQLAlchemy Version in Use

asyncpg 0.30.0
sqlalchemy 1.4.54

Database Vendor and Major Version

PostgreSQL 14

Python Version

Operating system

Linux

No se indica ningún archivo de origen ni ninguna prueba. Empieza reproduciendo la carga de metadatos de SQLAlchemy Table(..., autoload_with=conn) contra PostgreSQL 14 con asyncpg 0.30.0 y el OID indicado; después, sigue el tratamiento del parámetro OID. Se considera terminado cuando la carga de metadatos tiene éxito para OIDs por encima del rango de int32 sin DataError.
