Hello.
We do support Aurora postgres databases natively: https://docs.stacktape.com/resources/relational-databases/#a...
You can trigger lambda functions by a "cron" job (https://docs.stacktape.com/resources/lambda-functions/#sched...)
The only problem is that you need to package your lambda function yourself, as we currently don't natively support 0-config builds for Golang. (we can help you zip it, upload it to a deployment bucket, and effectively cache it tho).
