The normal array constructor should work: SELECT ARRAY[MIN(v),MAX(v),AVG(v),STDEV(v)] FROM (VALUES (1),(3),(4)) x(v); Not sure why this is better than using separate columns though. Maybe a new datatype and a custom aggregate would be easier to work with? -- Sam http://samason.me.uk/ -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
