I meant to add I think it may be possible to tell from the JDBC api if a
statement execution returns:

  - ResultSet
  - update count
  - other execution (e.g. DDL)

For the first two, ij does do the correct behaviour now. For the latter,
ij prints out the 0 rows inserted/upodated/deleted, but maybe it should
print out a simple 'statement executed'. Though I could never figure out
exactly how to tell from JDBC which type of statement it is.
