Hello,

I have a resultset that has many rows with bytea data.

It looks like me that when I iterate through the rows, the previous
rows are only garbage collectable when the resultset is closed, even
if I setup the statement like this:
statement.setFetchDirection(ResultSet.FETCH_FORWARD);
statement.setFetchSize(1);

Since it's bytea data, this fills up the memory very quickly. Any
thoughts on how to reduce this memory overhead and have the resultset
discard any previously fetched data?

Thanks for the help,

Geert
