If a table representing contact details can have 2 but no more than 2 email addresses is it really worth factoring-out email addresses to a separate table. Technically it's a 1-to-many relationship so should be done this way but what is the general practice out there in such "max. 2" situations? Keeping them as: Primary Email Secondary Email .... also preserves priority though not strictly normalised, I know. gvim -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
