Message-ID: <E1svxWB-001qYT-4N@gemulon.postgresql.org> (raw)
Add fastpaths for when no objects are found
If there are no objects found, there is no reason to inspect the
result columns and mallocing a zero-sized (which will be 1 byte
in reality) heap buffer for it. Add a fast-path for immediately
returning like how other object inspection functions are already
doing it.
