> When adding a new node to a cluster with big journal on PSQL database
> application runs out of memory on the new node and crashes (no exception,
> application exits with code 137).
> It's because with PSQL, when no fetchSize is specified, all the results of
> query are loaded into memory before being passed to application. Furthermore,
> specification of fetchSize only works in transactional mode and have no
> effect if autoCommit is true. (these are configured in ConnectionHelper)
