Why do I have 2 connections when im using 1 client? The command:

select * from pg_stat_activity


shows all currently active connections.
The database is hosted by AWS RDS and I am accessing the database with pgAdmin 4, thus I expect one other connection than mine and that is the rdsadmin, but it seems like I have 2 connections.

Output:

The second connection gets started when you start the query tool.
