Re: pgsql: Test conversion of NaN between float4 and float8.

Apologies Tom, I missed this; opossum is running one of its infrequent build runs now.

Test conversion of NaN between float4 and
float8.

Results from buildfarm member opossum
suggest that this doesn't work
quite right on that platform. 
We've seen issues with NaN support on
MIPS/NetBSD before ... allegedly they
fixed this stuff back in 2010,
but maybe only for small values of
"fixed".

If, in fact, opossum fails this test
then I plan to revert it;
it's mainly for diagnostic purposes
rather than something we'd
necessarily keep long-term.  I
think that the failures in window.sql
could be worked around with some code
duplication, but I want to
verify my theory about the cause
first.
