How to trigger an event when row column crosses now()? Is it somehow possible in postgres 12 to trigger an event when a table with an tsrange column crosses now(), or someone insert something that where the tsrange is prior to now()?
Triggers, as far i know, only triggers when someone insert or updates a row.
Triggering when someone insert a row which has passed now, seem to doable
With trigger that triggers on all inserts, but i am not sure how to trigger an event, when a given timestamp in that row crosses now..
And can both trigger scenarios be combined into one?
You'd have to schedule a program to run regularly and process the table.
Usually it is better to implement such logic in the SELECT statements.
