I was surprised to find out that apparently it's also a PostgreSQL
extension; standard SQL apparently disallows ORDER BY in VIEWs:
http://en.wikipedia.org/wiki/Order_by_(SQL)
When I found this out, I removed all the ORDER BYs from my VIEWs (which
had been there for the convenience of subsequent SELECTs).
Of course, where ORDER BY in a VIEW is really helpful, is with OFFSET
and/or LIMIT clauses (which are also PostgreSQL extensions), which is
equivalent to what you point out.
