On the other hand I want to try java.sql.Statement.setMaxRows(int).
Cayenne currently doesn't rely on this API, and I hope at least some
drivers implement "maxRows" support to smartly optimize the query. I
don't have too much hope here though, looks like we still will need to
generate correct SELECT.
