I see only two options:
1) Do nothing.
2) Move to Exceptions.
I've never used PDO and not set it to Exceptions, honestly. Adding more global
error conditions to code is a terrible idea, so let's not do warnings. If your
query breaks, you really shouldn't continue because your data is busted so your
following code will fail ungracefully at best, or corrupt data at worst.
Changing a default like this seems a reasonably safe thing to do in a major, as
long as it's still just as easy to switch back to silent mode for those who
prefer to be explicit.
