Sorry, one more question, the default strategy for the PostgresDialect is Sequence yet the table as I see it so far does not contain a table_column_sequence attribute. I noticed that sometimes Hibernate uses a hibernate_sequence variable in postgres to manage a table (but no others)....so I'm still confused right now how this really works.... Cheers!
