This has been suggested, and rejected, repeatedly.  It's not a good
idea to apply a driver-side band-aid to mask a server-side problem;
especially not when the driver does not have adequate information to
fix the problem properly.  (In other words, any driver-side solution
will fix some queries and break others.)

There will be a real solution in the backend someday soon, perhaps 7.4.
