Here's an updated patch with an extra regression test case that
triggers the issue.

I've also updated the function comment for expand_security_quals() to
better explain the situations where it actually has work to do --
tables with RLS and updates to auto-updatable security barrier views,
but not SELECTs from security berrier views. This explains why this
bug doesn't affect security barrier views (UNION ALL views aren't
auto-updatable), so only 9.5 and HEAD need to be patched.

Regards,
Dean
