Toggling The Pager In PSQL

When the pager is enabled in psql, commands that produce larger output will be opened in a pager. The pager can be enabled within psql by running \pset pager on.

If you'd like to retain the output of commands, perhaps as reference for subsequent commands, you can turn the pager off. As you might expect, the pager can be disabled with \pset pager off.
