Re: BUG #1169: Select table.oid from view seems to loop

This is an unqualified join, and will yield count(table1)*count(view1)
rows.  table1.oid is not exposed by the view and so you can't select
it from the view.  What you wrote is interpreted as
    select table1.oid from view1, table1;

I'm not surprised psql ran out of memory, but I'd have expected a more
graceful response than "crashing".  What happened *exactly*?  On my
machine, recent psql versions just discard excess data and then complain
later.
