hi.
explain(verbose) SELECT 1, 2, 3\; explain SELECT 1, 2, 3, 4;
will transformed to
explain(verbose) SELECT 1, 2, 3; explain SELECT 1, 2, 3, 4;
it seems to me your patch care about following position.
explain(verbose) SELECT 1, 2, 3; explain SELECT 1, 2, 3, 4;
^
but this patch [1] at another thread will get the top level statement
(passed the raw parse, no syntax error) beginning more effortless.
explain(verbose) SELECT 1, 2, 3; explain SELECT 1, 2, 3, 4;
^ ^
can you try to looking at [1]. it may help to resolve this patch problem.
