pq_fetch_all should return 'false' if result set is empty
Merge branch 'Searle-master'

pg_fetch_all should return a failure result if result set is empty.

libPQ gives the length of the escaped string *including* the null terminator.
This meant that the string constructed for the query contained a null byte and
libPQ would stop processing the query there.

The original phrasing made it sound like libpq was distributed with both Postgres and HHVM. This change should make the intended interpretation more obvious.
