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.
