INTEGER range ("-2147483648" is not accepted.)

Hi all,

I've found a bit strange thing on the INTEGER range in the official manual.

http://www.postgresql.org/docs/8.4/interactive/datatype-numeric.html

According to the official manual, the INTEGER range is "-2147483648 to +2147483647".
However, my example in below shows that "-2147483648" is not accepted.

Is this correct? Any suggestions?

Regards,
