You may receive a NOTIFY with DataSnap via dbexpress driver?

You can't receive NOTIFY automatically using dbExpress driver.
You should manually read NOTIFY from a table in a separate thread.

We do not have any driver with such functionality.

As an alternative, you may use the PgDAC functionality, established in the TpgAlerter component, for getting notify events from PostgreSQL. For more details on using TpgAlerter, refer to our online documentation: ... lerter.htm

To learn more on our demo project, where this functionality is shown, please follow the link below: ... _pgdac.htm
