The fourth and final method is to use the lsof command. This method is less reliable than the first two as the postgres process could be running but not accepting connections. This command will show all running processes and can be used to check if the postgres process is running. The third method is to use the ps command. This method is less reliable than the first as Postgres could be running but not listening on the default port. This command will show all active network connections and can be used to check if the Postgres port is listening. The second method is to use the netstat command. This is the recommended method for checking if Postgres is running.

This can be done in a number of ways, each with their own benefits and drawbacks. => Successfully started `postgresql` (label: is not uncommon for a Linux user to need to check if Postgres is running. => Your postgresql 12 data remains at /usr/local/var/postgres.old => Upgraded postgresql data from 12 to 13! Running this script will delete the old cluster's data files: Once you start the new server, consider running: Optimizer statistics are not transferred by pg_upgrade so, Restoring database schemas in the new clusterĬreating script to analyze new cluster ok Restoring global objects in the new cluster ok Setting frozenxid and minmxid counters in new cluster ok
