/*
When a multiple key conflict happens in a REPLACE command mysql
expects the conflicts to be reported in the ascending order of
key names.
For e.g.
CREATE TABLE t1 (a INT, UNIQUE (a), b INT NOT NULL, UNIQUE (b), c INT NOT
NULL, INDEX(c));
REPLACE INTO t1 VALUES (1,1,1),(2,2,2),(2,1,3);
MySQL expects the conflict with 'a' to be reported before the conflict with
'b'.
If the underlying storage engine does not report the conflicting keys in
ascending order, it causes unexpected errors when the REPLACE command is
executed.
This flag helps the underlying SE to inform the server that the keys are not
ordered.
