For myself, it isn't so much a rush as a sense that the code out there 
that will break, will never change unless forced, and any time seems 
better than never.

Correct me if I am wrong - but I think this issue represents an 
exploitable SQL injection security hole. I switched because I convinced 
myself that the ambiguity of \' represented actual danger. I'm concerned 
that if the web front end doing parameter checking and passing in code 
using either '' quoting or \' quoting can be exploited if the server 
happens to be configured the opposite way. To me, this ambiguity can 
only be addressed by everybody agreeing on the right way to do it, and 
'' quoting seems like the right way to do it to me.

Cheers,
mark
