You're absolutely correct, I though the serial name was also reported
in psql, but no, only in pgadmin, so, like you said, in postgresql
there are only int4 and int8.
Which means we (or the driver maintainers, to be more precise) must
choose, postgresql complaint (int4) or jdbc complaint (serial)...
But changing this type of things is not nice for applications ...
