Hello

For sending and getting notification, you should use TUniAlerter:

Getting:

begin
  UniAlerter1.Events := 'pg_uni_alerter'; // any name
  UniAlerter1.Start;
end;

Sending:

begin
  // second parameter is supported in PostgreSQL 9.0 and higher
  UniAlerter1.SendEvent('pg_uni_alerter', 'message'); 
end;
