Обсуждение: type "serial" and biginteger

Hi all,
I create a table with Primary Key with name "gid" and type SERIAL.
I have a dubt on the SERIAL type: this data type is a INTEGER (int4)
type, but the sequence that is automatically created with pgAdmin has
BIGINTEGER output (MAXVALUE 9223372036854775807).
This fact can cause a numeric overflow during the insert?

Version Postgres 9.0.3.
Thanks in advance,
Domenico.

yup -- if you're really worried about this, use BIGSERIAL.  you could
in theory cap the sequence, but you'd just be trading one error for
another.
