Why would one need a Primary Key... which can only be declared at table creation if one can create a Unique Index post table creation? ie: I deleted my primary key... is that a big deal? What's the purpose of the Primary Key if it's function can be duplicated with another Unique Index? thanks, ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://www.postgresql.org/search.mpl
