It looks like the text-to-float4 converter function is not NULL-safe in
7.0.*. Sorry about that :-(.
7.1 fixes a boatload of problems of that ilk. In the meantime you could
kluge up something with a CASE expression that tests for null before
trying to cast to float4, or you could fix text_float4 to check for a
null input.
