hello greg,
the thing with statement_timeout is a little bit of an issue.
you could do:
SET statement_timeout TO ...;
SELECT FOR UPDATE ...
SET statement_timeout TO default;
this practically means 3 commands.
the killer argument, however, is that the lock might very well happen
ways after the statement has started.
imagine something like that (theoretical example):
SELECT ...
FROM
WHERE x > ( SELECT some_very_long_thing)
FOR UPDATE ...;
some operation could run for ages without ever taking a single, relevant
lock here.
so, you don't really get the same thing with statement_timeout.
regards,
hans

Can't you to this today with statement_timeout? Surely you do want to
rollback the whole transaction or at least the subtransaction if you
have error handling.
