Re: Error in trying to dump any database

Hi,

I recently had a similar problem (7.1.2) and I suspect you are suffering
the same. It turned out to (probably) be a compiler optimzation problem.
I could do

select int4(4::int8/4::int8);

and it would work on a machine compiled under gcc 2.95.2 but failed with
"int8 conversion to int4 is out of range" on a box comiled under 2.7.2.1.

My problem was with int84() and its offending code is almost identical to
dtoi4() which is this little piece of goods here.

if ((num < INT_MIN) || (num > INT_MAX))
elog(ERROR, "dtoi4: integer out of range");

If I were you I'd change this to

if (num < INT_MIN)
elog(ERROR, "dtoi4: integer out of range - too small");
if (num > INT_MAX)
elog(ERROR, "dtoi4: integer out of range - too big");

recompile and the (hopefully) watch the problem go away.
