This note is in Hasura.Metadata.Class. It is referenced at:
Postgres tables’ event triggers and scheduled event triggers are similar in the core logic. But currently, their implementation is completely isolated and do not share a common schema in Postgres. We’re having a plan to simplify them via a common ‘event storage and retrieval’ interface (maybe via a Postgres extension?). This will potentially reduce number of interactions made to database and schema foot print.
