this rule should be simply removed. It's not problem. The people long time believe so row cannot be null ever. I don't know if this is from Oracle or somewhere. SQL/PSM allows it. This semantic is little bit difficult. There is rule so any object is NULL when all fields is NULL too. I thing, so it's true. There is object, that has zero information. When You thinking about it, you have to forgot any your knowledges from languages that's knows pointers. Maybe some people has problem, because they put in equality NULL from SQL and NULL pointer. regards Pavel Stehule -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
