So, as far as I understand, you want asynchronously processing data with a process that can be started manually and/or periodically. I'm probably unable to see what is the goal, but I would go for a combined solution: 1) a trigger that notifies an external process <https://www.postgresql.org/docs/current/sql-notify.html> 2) the process runs when notified (by the trigger) or when started manually or when started by pg_cron (one per minute). Of course the process is "internal", so something like a stored procedure (at least as entry point). The problem with such solution is about race conditions (what if you manually start something that is already running?), but I guess you had this problem on the oracle side too. Hope this helps. Luca
