Yeah but anything holding a lock that long can be terminated via
statement_timeout can it not?

Well, no?  statement_timeout is per-statement, while transaction_timeout
is, well, per transaction.  If there's a process which is going and has
an open transaction and it's holding locks, that can be an issue.

No, what I mean is this:

select * from foo;
update bar;
delete baz;

Each one of those is subject to statement_timeout, yes? If so, then I don't see a point for transaction timeout. You set statement_timeout for what works for your environment. Once the timeout is reached within the statement (within the transaction), the transaction is going to rollback too.
