       SELECT a, c, d    FROM (SELECT a, b, c FROM my_table) AS my_view, other_table           WHERE my_view.a =
other_table.a          AND other_table.x = 'foo';
 

I'm still not detecting a problem here ... if selecting from a view
*doesn't* act exactly like a sub-SELECT, it'd be broken IMHO.

We're not that far away from being able to do this, and it looks more
attractive to work on that than to hack the rewriter into an even
greater state of unintelligibility ...
