Streaming Replication Postgresql 16

Hi,

Do the below processes look OK for a standby (streaming replication) server? We recently migrated from 12 to 16. I don't remember seeing "startup recovering"  process for a long time after starting of standby server on postgresql 12, it has been long time so I could be wrong.  Just want to make sure my standby is in a good shape. I have run some queries on standby to see if latest data is available and seems like it is there.

postgres   16909       1  0 May15 ?        00:00:00 /usr/lib/postgresql/16/bin/postgres -D /var/lib/postgresql/16/main -c config_file=/etc/postgresql/16/main/postgresql.conf

postgres   17012   16909  0 May15 ?        00:03:04 postgres: 16/main: walreceiver streaming 85/E24B6000

Also seeing log entries about every 5 minutes as shown below. These were not present when we were running 12.
