Bugs fixed:
Incompatible Change:
INSERT DELAYED statements are not supported
for MERGE tables, but the
MERGE storage engine was not rejecting such
statements, resulting in table corruption. Applications
previously using INSERT DELAYED into
MERGE table will break when upgrading to
versions with this fix. To avoid the problem, remove
DELAYED from such statements.
(Bug#26464)
