We're talking about system-to-system pulls and pushes.

For example, maybe your product needs to process data from your customers' sales and customer support systems. In that case you can have automatic updates show up in Postgres from your customers' Salesforce and Zendesk instances. Does that sense?

Alternatively, many products want to the ability to push data to their customers' systems. For example, suppose you're a billing software vendor showing data in your own portal that customers log in to. Your customers may also want you to automatically push this data to their accounting systems or data warehouses so that they can do their own analysis.

Does that make sense?
