For integers (optional sign and all digits), the code in
src/backend/parser/scan.l uses strtol() to read the string, then checks
for failure. If it fails, the number is interpreted as a double float on
the assumption that if it could hold more digits it would succeed!
Anyway, either strtol() thinks it *should* be able to read a 64 bit
integer, or your machine is silently overflowing. I used to have a bunch
of these boxes, and I recall spending quite a bit of time discovering
that Alphas have some explicit flags which can be set at compile time
which affect run-time detection of floating point and (perhaps) integer
overflow behavior.
Can you check these possibilities? I'd look at strtol() first, then the
overflow/underflow flags second...
