Autovacuum's 'workitem' request queue is of limited size, so requests can fail if they arrive more quickly than autovacuum can process them. Emit a log message when this happens, to provide better visibility of this. Backpatch to 10. While this represents an API change for AutoVacuumRequestWork, that function is not yet prepared to deal with external modules calling it, so there doesn't seem to be any risk (other than log spam, that is.)
