We want to start processes controlled by a prostgres table which acts like crontab.
So we want to start a background worker process which starts the defined functions.
Is it possible to start from a background worker process a child process with a specific User. So this process can only acces the data for his authority.
Like a SQL Intrusion with this definition nobody can start a process a Postgres superuser.
Already exists a "crontab like" background worker project [1].
