That's not warranted here IMNSHO. There is an asynchronous API for
dealing with these types of situations. Given that the blocking
execution functions do not take a timeout parameter and depend on
unreliable facilities, unbounded execution time should be expected.

Writing robust libpq applications generally involves using the
asynchronous API. It's better in just about every way except
easiness.
