This really depends on how you implement the global statement cache and
management. All the compiled plans can be stored in the cache. The plans can be
reused, if possible (the reused plans might not be identical).
The plan recompilation in this PR can be part of global statement cache and
management. Plan recompilation can be manual or automatic. In this specific
case, it should be done automatically.
