I'm not sure what you mean by "inherits sequence", may be you mean "inherits default values" ( specifically on serial ) ? I do not know the reason, but that is what the docs are for. You hit a glitch, you RTFM a bit before spamming the bugs list. Then you consider it a short coming and ask about it / request a feature on the general / hackers list where more knowledgeable people may give you some insight ( they tend to be busy, and may see it and dismiss it as "another one who does not bother to read the docs ). If you see it as a feature, why do you report it as a bug? > Euler Taveira Timbira - > http://www.timbira.com.br/ > PostgreSQL: Consultoria, Desenvolvimento, Suporte 24x7 e Treinamento And, given your sig, you should have done it. I'm just an ocasional user and found it in the docs in about a dozen seconds. Francisco Olarte.
