Yes, You can, but I don't know result of this. ;) One day I worked on
couple of patches, maybe I have those somewhere to acquire this what I
assume You want.

I assume, You want your transaction to proceed when error will occur.
Yes you can make some change to ignore this, but this will not give you
expected behaviour, because error is generated on server side, and
server will rollback transaction.

But please specify more details mainly what You want achieve and what
are preconditions.
