Well, look at this from this point of view: EnterpriseDB implemented this because of customer demand (presumably). Fujitsu also implemented this for customers. The pgjdbc driver implemented this for its users. Now 2ndQuadrant also implemented this, and not out of the goodness of our hearts. Is there any room to say that there is no customer demand for this feature? -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
