If you want a 2017 partition, then FOR VALUES FROM ('2017-01-01') TO ('2018-01-01') will allow all 2017 timestamps and only 2017 timestamps. You've no need to consider precision of the type and how many 9's you add to anything here. -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
