pgAgent is a job scheduler for PostgreSQL which may be managed using pgAdmin. Prior to pgAdmin v1.9, pgAgent shipped as part of pgAdmin. From pgAdmin v1.9 onwards, pgAgent is shipped as a separate application.
pgAgent is available as a StackBuilder add-on package if you use EDB's Installers for Windows, Mac and Linux, as a Debian package from apt.postgresql.org, or an RPM package from yum.postgresql.org. Alternatively, source packages can be download below.
