The risk to anyone not using serializable transactions is most
definitely zero. I've been running with this patch in my daily
tests (including the isolation tests and `make installcheck-world`
with default_transaction_isolation = 'serializable' without seeing
any problems. The best way to check would be to run the isolation
tests on a platform reporting the overflow.
