I think the argument was that it's almost certainly a mistake, so we're more helpful by throwing an error than by silently executing a query that probably won't do what the user was expecting. In this particular example, it seems quite likely that the programmer meant "foo" (ie a quoted column reference) and got the quote style wrong ... regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
