Can you do that in postgres? Will it really make the DDL atomic? I know that is oracle any DDL will implicityly commit any existing transaction, start another one, and commit again at the end of the statement. I think it is similar in SQL Server too. Can postgress really do DDL on multiple tables and indexes atomically? ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
