At this point, my question is: do we want to support the lsn data type idea or

Personally I think a function is enough - it solves the only case that
I've actually seen. But a datatype would be a more complete solution,
of course - but it seems a bit of an overkill to me. Not really sure
which way we should go - I was hoping somebody else would comment as
well..
I too think a datatype is overkill, if we're only planning on providing
one function.  Just emit the values as numeric and have done.

                        

+1.
