This commit is just fixing the over-sight caused by commit a453004, as anyways for QE reader case we will return much earlier in function and never ever reach here."},"comment":{"url":"https://api.github.com/repos/greenplum-db/gpdb/issues/comments/261173851","html_url":"https://github.com/greenplum-db/gpdb/pull/1337#issuecomment-261173851","issue_url":"https://api.github.com/repos/greenplum-db/gpdb/issues/1337","id":261173851,"user":{"login":"ashwinstar","id":11396815,"avatar_url":"https://avatars.githubusercontent.com/u/11396815?v=3","gravatar_id":"","url":"https://api.github.com/users/ashwinstar","html_url":"https://github.com/ashwinstar","followers_url":"https://api.github.com/users/ashwinstar/followers","following_url":"https://api.github.com/users/ashwinstar/following{/other_user}","gists_url":"https://api.github.com/users/ashwinstar/gists{/gist_id}","starred_url":"https://api.github.com/users/ashwinstar/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ashwinstar/subscriptions","organizations_url":"https://api.github.com/users/ashwinstar/orgs","repos_url":"https://api.github.com/users/ashwinstar/repos","events_url":"https://api.github.com/users/ashwinstar/events{/privacy}","received_events_url":"https://api.github.com/users/ashwinstar/received_events","type":"User","site_admin":false},"created_at":"2016-11-17T07:21:07Z","updated_at":"2016-11-17T07:21:07Z","body":"Glad its helpful.
