CI3 and PHP8.1(ctype_digit(): Argument of type int will be interpreted as string in the future)

[Obata2024]

When trying to use PostgreSQL under the given conditions, the following error occurs:

A PHP Error was encountered
Severity: 8192

Message: ctype_digit(): Argument of type int will be interpreted as string in the future

Filename: postgre/postgre_driver.php

Line Number: 98

Should I modify the postgre/postgre_driver.php file to resolve this? If it’s acceptable, I can submit a PR.

Also, has anyone resolved the same issue using an override?
I attempted to create a custom class under the application/core directory to override it, but this error still persists.

Looks to me that the ctype part of that if statement should just be removed. As far as I can see so far none of the other drivers check anything other than that the value isn't empty before using it.
