That seems to me to be just confusing the issue.  Now the table name
and the view name are just totally different with no obvious
connection between them.  We have enough nonsense of this type already
(e.g. pg_stats vs. pg_statistic; pg_authid vs. pg_roles vs.
pg_shadow).  I think we need to settle on a system for handling
problems of this type and document it in the fine manual or perhaps a
README somewhere, and stick with it.  Inventing random unconnected
names is just craziness.

Now, if you/others don't like my _view convention; that's fine.  Just
pick something else.  Really, I don't believe the tab-completion thing
is much of a problem, you just type underscore-tab and you're there.
But I am 100% OK with whatever we pick, as long as it is something
easy to remember that we have a chance of being able to apply
consistently.
