Not as part of this patch. Of course, once delta relations are available, who knows what people might do with them. I have a hard time imagining exactly how you would expose what you're talking about, but a column to distinguish before and after images might work. Incremental maintenance of materialized views will require that in the form of a count column with -1 for deleted and +1 for inserted, so there might be some common ground when we get to that. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
