PostgeSQL Schedule Jobs

I am looking a way that can give the ability to schedule jobs on PostgreSQL, for example to schedule execution of some procedures or statements based on interval or on specific schedule. I tried already the pg_agent but this is a service running in local pc and which enables a schema in PostgreSQL. As a result this cannot be used for remote instances or managed instances. I am looking a way that they can be triggered from the database context and not from another runtime. Any ideas?
