Hmm I was not aware of those macros, or that I was breaking portability conventions for postgres. If you could direct me as to where I could read up on these things, I would be more than willing to learn about them.

I actually figured my own problem out, thank you for pointing out that is was likely not in the code, I found I was missing one of the declaration statements needed by postgres.

Once again any links to where I can read up on postgres coding conventions would be great as I have to write a few more of these custom data types. I have read through the manual but I am guessing that I missed a section.

Thanks,
Morgan
