This is exactly the solution. What is the due date of the current development driver ?

The JDBC javadoc implies that calling insertRow() leaves the resultset
on the insert row. This is what the driver implements.

As the javadoc says, getRow() returns 0 if there is no current row.
You're on the insert row so there is no current row.

What is the exception you see?
The current development driver (see jdbc.postgresql.org) will treat
absolute(0) as if you'd called beforeFirst(). O lder drivers might do
something different.

Looking at the driver source, it looks like the newly inserted row is
appended to the resultset, so you should find it at the end of the
resultset not the start. (I don't think making this assumption is
portable, though).
