Re: [Fwd: Re: Serialize]

Barry,

Well you know my vote!

Just to re-iterate:

1) I don't think it belongs in the driver
2) I think there are better ways of doing it

No I haven't had a chance to look at the xa code yet

Dave

Dave,

I share your concerns about this functionality. In fact last month I
wrote the following in response to a patch to this functionality.

I wouldn't mind this being pulled out of the main code line for now and
moved to contrib until it becomes more robust.

There are two areas in the current code that I am uncomfortable with.
This serialize code and the code in org/postgresql/xa. Have you looked
at the xa code?

thanks,
