Thread: PQclear question...
Is it necessary to call PQclear if a query that
would normally return tuples fails? What if the
query returns 0 tuples? In other words, is it
only necessary to call it if you get back one
or more tuples?

If you got a non-NULL result from PQexec, you'd better PQclear it,
or suffer the consequences (memory leak -> eventual application crash).
