Hi Michael,

Thanks for this! I had in the back of my head that there would be two
changes that may affect PostGIS - one was the VARLENA macros above, and
another was a change in the index opclasses. However, if it passes
regression for you then that's great.

I'll have a look at this over the next few days, and get it into a form
that we can commit to SVN.

Many thanks,
