We could do this in the driver to make it for the older backends (we are going to support 7.3 and 7.2 in the 74 driver still). On the other hand, people using 7.3 backends have other non-SQL compliances that we cannot mask with the driver, so I wonder if this is worthy of the extra if statement. But that is for Barry and Dave to decide, if someone submits a patch. Regards, Fernando -- Fernando Nasser Red Hat Canada Ltd.
