Yep, it is a bug, and I will add it to the TODO list. In float8out, we
use:
printf("%.*g", CONST, value)
and the %g is causing it to print as:
equal to the precision. Trailing zeros are removed from the
fractional part of the result; a decimal point appears only if it
is followed by at least one digit.
Now, what we should probably be doing is to allow -1 (without decimal
point) to be promoted to float8 in the INSERT, and I think we are going
to be able to do that in 6.4.
I know this is crummy, but I can't even think of a workaround for it.
