Clear The Screen In psql

The psql interactive terminal does not have a built-in way of clearing the screen. What I usually do if I really need the screen cleared is quit, run clear from the shell, and then open a new psql session. This is unnecessary though. Instead, we can use the \! command to execute a shell command, in this case, the clear command.

> \! clear

This clears the screen in one step and keeps our current session running.

See the psql docs for more details.
