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.
