--------------------------------------------

Patch merged to master. Hi [~janulatha] Can you provide the patch for branch-2 as well? The
qfile from the patch fails on branch-2.

> A view is a virtual structure that derives the type information from the table(s) the
view is based on.    If the view definition is altered, the corresponding column types should
be updated.  The relevance of the change depending on the previous structure of the view is
irrelevant.
