Pull Request: php8.4: Fix the title and RFC link of PDO driver specific subclasses by takaram · Pull Request #1154 · php/web-php · GitHub
Author: takaram

PHP 8.4 has accepted two RFCs with similar titles, and they seem to be mixed up.

- PHP: rfc:pdo_driver_specific_subclasses
- PHP: rfc:pdo_driver_specific_parsers

This PR also adds `Pdo\Pgsql` class in the list of new PDO subclasses.
