There's not a standard way, but we do have an extension method that does
the job: getResultStatusString()

This method was added as someone else asked for it in the distant past.

ie:
Statement st = conn.createStatement();
.. your code that either runs st.executeQuery() or   st.executeUpdate() ..

then for JDK1.1.x:    String returncode = ((postgresql.jdbc1.Statement)st).getResultStatusString();

or for Java2:String returncode = ((postgresql.jdbc2.Statement)st).getResultStatusString();

PS: Sorry, you have to state the driver version (jdbc1 or jdbc2), although
this will be fixed in 6.6, and will become postgresql.Statement.
