Postgres: After importing production database (with replication) to my local machine, I notice network packets being sent and received from macbook

Question

I\'ve been a MySQL guy, and now I\'m working with Postgres so I am learning. Wondering if someone can tell me why my postgres process on my macbook is sending and receiving data

Answer 1

If it's UDP traffic, to and from a high port, it's likely to be PostgreSQL's internal statistics collector.

These are pre-bound to prevent interference and should not be accessible outside of PostgreSQL.
