I am confused how this relates to the 16-parameter limit mentioned in
the message. Is it limited to 16 columns of a composite type?

I do remember a discussion. Certain heavy users are using
object-oriented programming routines and 16 is too small. I know of at
least two big users, Ben Adida (OpenACS), and Josh Berkus, who would
like the limit increased. They can increase it themselves, but because
they distribute source to others, all installs then have to have the
modification. I think they would be happy with 24.
