Autovacuum has a mechanism to be requested work -- grep the tree for AutoVacuumRequestWork and AutoVacuumWorkItemType. Currently its only use is BRIN autosummarization, but it's possible to add others by patching the core code. If you want to propose the idea of making it extensible, I think it would serve not only your present use case but plenty of others, too. -- Álvaro Herrera Breisgau, Deutschland — https://www.EnterpriseDB.com/
