It might well be reasonable to redefine statement_timeout as limiting the
total time from the first client input to the response to Sync ... but
if that's what we're doing, let's make sure we do it consistently.
I haven't read the patch, but the comments in this thread make me fear
that it's introducing some ad-hoc, inconsistent behavior.
