Subqueries and derived tables (unnamed views).
INSERT ... ON DUPLICATE KEY UPDATE ... syntax. Note that this does note exist in postgresql but if we decide we need this then a CREATE RULE ... ON INSERT ... INSTEAD might or might not help (needs to be done per table if I understand this). Later :)
GROUP_CONCAT Again, not standard and the only solution for pgsql I know requires plpgsql
