To make a PostgreSQL table real-time, you can use a combination of triggers and stored procedures. Here is a general outline of how you can achieve this:

  1. Create a trigger function: First, you need to create a function that will be triggered whenever a specific event occurs on the table. This function will be responsible for updating the data in real-time.
1
2
3
4
5
6
7
CREATE OR REPLACE FUNCTION update_realtime_data()
RETURNS TRIGGER AS $$
BEGIN
  -- Your update logic here
  RETURN NEW;
END;
$$ LANGUAGE plpgsql;


  1. Create a trigger: Next, you need to create a trigger that will call the trigger function you created above whenever a specific event occurs on the table.
1
2
3
4
CREATE TRIGGER trigger_name
AFTER INSERT OR UPDATE OR DELETE ON your_table
FOR EACH ROW
EXECUTE FUNCTION update_realtime_data();


  1. Enable the trigger: After creating the trigger, you need to enable it on the table.
1
ALTER TABLE your_table ENABLE TRIGGER trigger_name;


By following these steps, you can make a PostgreSQL table real-time by updating the data automatically whenever a specific event occurs on the table.
