I would prefer distinct type or domain specific defaults, but until we have that I would settle for datatype specific defaults. Defaults, not only permissible settings. Most people don't keep same data in float8 as they do in int4, but neither of those were ones I was thinking about. I see 3 main classes: * data with small number of distinct values (e.g. boolean, smallint) * data with many distinct values * data with where every value is typically unique (e.g. text) -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
