[VOTE] Use exceptions by default in SQLite3 extension

Hi Illia,

thank you for your feedback.

This is actually what I did, first, but I changed after feedback from
@Girgias:

https://github.com/php/php-src/pull/11058#discussion_r1162723112

You are likely to get push back not just from myself if you propose
it as such in an RFC

I don't have a strong opinion one way or another. I just felt it was
more coherent (with PDO) to use RuntimeException.

The PDOException class is actually extending the RuntimeException,
not just Exception.

Yes, and this is, IMHO, a mistake.
Outside SPL, there are only 4 extensions which extend from RuntimeException:

• PDO
• MySQLi
• SNMP
• Phar

See:
https://heap.space/search?project=php-src&full=&defs=&refs=spl_ce_RuntimeException&path=&hist=&type=

The vast majority of extensions that define their own custom exceptions
extend Exceptions.
The reason being that depending on a separate extension (here SPL) instead
of core API is less than ideal.

Moreover, SPL exceptions are meant for userland.
And I personally find it extremely strange that if I attempt to catch a
RuntimeException I might as well catch a PDO failure.

Best regards,

George P. Banyard
