Boolean column stick to "false" after calling updateRow() onupdateable ResultSet - Mailing list pgsql-jdbc

Hi,

I've observed something unexpected when migrating an application from
PostgreSQL-8.4.21 & postgresql-8.4-701.jdbc3.jar to PostgreSQL-12 &
postgresql-42.2.9.

With the updated software-stack boolean columns always seem to stick
to "false" after updateRow() is called on updateable ResultSets.
The value stored however is correct, and calling refreshRow() right
after updateRow() seems to restore the "old" behaviour and restores
the value set a few lines aboce.

I could fix the issue simply by forcing the additional roundtrip
caused by refreshRow - however I still wonder - is the observed
behaviour conformat to the spec / to be spected?

Thank you in advance & best regards, Clemens


//DDL
CREATE TABLE sometable (id integer NOT NULL, someprop boolean DEFAULT false);

//JDBC access
        Statement st =
connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
        ResultSet rs = st.executeQuery("SELECT * FROM sometable WHERE id=...");
        rs.next();
        System.out.println(rs.getBoolean("someprop")); // value stored in DB
        rs.updateBoolean("vereinsFlugzeug", true);
        System.out.println(rs.getBoolean("someprop")); //Matches the
value set above (true)
        rs.updateRow();
     //   rs.refreshRow();   //fetches the value stored
        System.out.println(rs.getBoolean("someprop")); // always returns false.
