System catalog accesses are generally done with SnapshotNow semantics
--- in particular, lookups for function definitions will be done that
way. Although the PL languages all cache function definitions, they go
out of their way to verify that the cache is still up-to-date each time
it is used. I don't recall the exact example that made us conclude we
had to act that way, but it's unlikely to be changed.
