The discovered memory leak was introduced by the commit
762bf7a03b
(MDEV-22602 Disable UPDATE CASCADE for SQL constraints)
The reason why a memory leaked on running the test main.constraints
is that a statement arena was used for allocation a memory
for storing a constraint name. A constraint name is an entity having
temporary nature by its design so runtime arena should be used for its
allocation.
