When you're done using a connection. :)

Never.  This is obsolete.

I suspect you aren't asking the right question.

I'm gonna guess you're asking:

"What do I need to do to see database updates (made by other
clients/connections)?"

The answer to that question is:

To see database changes, you need to start a new transaction.

You always see data as of the time the current transaction started.
