Re: Implementing an expanded object in C

Thanks Andrew, sorry for my late reply it took me a while to get time to
analyze the issue.

You are of course correct, I had confusion around the create type
statement, but the good news is, I have figured out the final ins and outs
of creating an expanded type, and my matrix type can now be used as
variables plpgsql functions and works great! Thanks to you and Tom and
everyone else who helped me get unblocked and making progress.
