Tom, that was only a modification for the client-side libpq. The PG is standard, we are using both 9.4 and 9.5 that were officially released.
I guess there is no standard test for the scenario. But if such test was created (for checking the format of the returned arrays) it would fail. Maybe I'm wrong, I'm not sure.
The only issue currently is a slow performance on parsing text representation. Whole point of my question was why PG does not return binary formatted field when requested (this is a feature supported in the protocol).

Um. I'm not that excited about supporting bugs in modified variants of PG. If you can present a test case that fails in stock community source code, I'll be happy to take a look.
