The bug this thread is about was actually visible in regression test
output, as the wrong output of pg_rules output. As were a number of
previous bugs. So it seems time to actually make sure that the output of
the rules we generate to test deparsing actually do something remotely
sane, by executing the deparsed sql. Obviously human inspection is not
sufficient. You can do so by executing deparsed output of a rule or a
view (both should be doable afacis).
