Rodrigo,
You could use LISTEN + NOTIFY with triggers.
In after_insert_statement trigger you could notify a listener, the client could query it immediately.

Subject: [PERFORM] Best way to check for new data.
I have a table that holds entries as in a ficticious table Log(id integer, msg text).
Lets say then that I have the program log_tail that has as it´s sole purpose to print newly added data elements.
What is the best solution in terms of performace?
Thank you for your time,
Rodrigo
