Is there an aggregate that will return an arbitrary instance? That is, not necessarily the max or min, just any one? (Which might perform better than max or min) More importantly: Is there one which will return an arbitrary instance as long as it's not NULL And even better: An aggregate which will return the first instance that meets a certain predicate? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
