Improvements to the redshift_maintenance macro, namely:
Ability to add a version of vacuumable_tables_sql to your own project to override the default
Confirm the existence of a relation before trying to vacuum it -- previously if a relation was dropped in the time between generating the list of tables, and vacuuming the relation, you'd hit a database error and the whole job would error out. We're now avoiding that scenario.
