Hello,
Does PostgreSQL supports some database change notification mechanism?
I have Java Swing application and PostgreSQL database for storing data.
The problem is that my database can change at any moment and instead of
querying
the database every 5 seconds, I would like the database to some how send my
application
a notification of a change when it happens.
I would appreciate if someone can give me example how to accomplish it
between JDBC and PostgreSQL.
Thanks.
