Notice vs. debug doesn't seem very important as you usually don't build
with debugging enabled unless you're really running in a controlled
environment.

I think it's a notice because at liblwgeom level there's only ERROR or NOTICE,
no way to specify something else. Anyway this is at postgis level, so it should
be easier (altought you'd still get NOTICE from liblwgeom).

See the macro implementation for POSTGIS_DEBUG and POSTGIS_DEBUGF.
Feel free to send a patch once you're happy with it.
