And:
set statement_timeout = 20;
query_with_error;
set statement_timeout = 0;
COMMIT;
That will have to change in autocommit off to:
BEGIN;
SET statement_timeout = 20;
query_with_error;
SET statement_timeout = 0;
COMMIT;
I assume that BEGIN does start a transaction. With no BEGIN above, the
big problem is that it will work most of the time, but when/if the query
fails, they will find out they forgot the BEGIN.
