Specifies whether to enable the vacuum boost option for all VACUUM commands run in a session. If `enable_vacuum_boost` is `true`, Amazon Redshift runs all VACUUM commands in the session with the BOOST option. If `enable_vacuum_boost` is `false`, Amazon Redshift doesn't run with the BOOST option by default. For more information about the BOOST option, see [VACUUM](r_VACUUM_command.md).
