    I am for it, lets discuss the details. Having a db-agnostic
    SequencePkGenerator is a good start. I was thinking about moving in this
    direction for some time, since mechanism for PK generation ideally should
    take into account 2 things - database support for a particular feature and
    user preference to use a particular mechanism.

    Currently we are only taking the former into account (EOF way of thinking I
    guess :-)). Eventually we must support the later too.
