Asked by Kaushalya Pradeep
DigitalOcean support pg_cron extension for managed Postgres database service,
but we cannot use it since we cannot change the extension’s database since we cannot change the postgresql.conf, so extension can only be used with defaultdb. Typically using defaultdb for applications are discouraged, So my question is what is the use case pg_cron extension on DigitalOcean?

Hello @kaushalyapradeep
You’re correct,
pg_croncan be used on the DigitalOcean managed Postgres service, but only on thedefaultdbbecause thepostgresql.conffile is not user-configurable in the managed service. Using thedefaultdbis typically discouraged for applications for separation of concerns and better management.However,
pg_croncan be quite useful in a number of scenarios like performing routine maintenance tasks (clean-up, vacuuming, etc.), running regular data analysis queries, generating reports, and more, all on a specified schedule.While it might not be ideal for all application scenarios due to the limitations you pointed out, it offers some handy automation capabilities within those parameters.
Hope that this helps!
