Brooke Beacham wrote > (without having to replicate/maintain a table of columns separately from > the system catalog) Just create the friggin' table and wrap whatever logic you want in a view (or functions) so that you at least get usable results/defaults for any columns you haven't added. Any solution you pick has the risk of becoming out-of-sync so tossing out the best solution does more harm than good. In terms of "group" columns you might just consider creating two tables that have a one-to-one relationship to each other (or three, the base table and then group A and group B tables). A lot depends on the why and structure of your model but there is no standard facility for custom column meta-data and though the comment facility can be used for this I much prefer to leave that for human consumption and have something more structured and easily customize-able for meta-data.
