Commit59f2971

committed

Fixes:

This patch forces postgres95 to assume any floating-point value is afloat8. It removes the requirement that you cast all floating-pointconstants to float8.We can remove alot of casts in the regression test after we are surethis works.If I have missed anything, would someone let me know. I have testedinserts of floating-point values into float8 fields, and it worked well.Casting the number to float4 showed the same precision loss as previousuncast values showed.Submitted by: Bruce Momjian <maillist@candle.pha.pa.us>
