Since pg_cron is now supported in PostgreSQL 12 managed db, what would be the best way to use it if we have a database that is not defaultdb? Currently you can only install the pg_cron extension into defaultdb. Since pg_cron uses libpq, you can also run periodic jobs on other databases or other machines but you have to be a superuser so that is ruled out. Foreign Data Wrappers are the only other option I can see, but that seems like an unnecessary complication. I’d like to be able to just install the extension into my database but this requires modifying postgresql.conf to add cron.database_name.

Hi there,
Thank you for reaching out to DigitalOcean Support.
I understand you are able to install the pg_cron extension in the defaultdb database but when trying to install the extension in another database returns error.
Unfortunately that’s currently not something that is user configurable as pg_cron only supports one database at a time and the only DB we’re sure to exist at creation time is the default one. (https://github.com/citusdata/pg_cron/issues/89)
