And when $query is:  "insert into foo values (...); select * from bar;"

You will get:
DECLARE jdbcXX CURSOR FOR insert into foo values (...);
select * from bar;
FETCH FORWARD $fetchSize jdbcXX;

Which clearly isn't what you want.

So like the discussion that we had on when we should/could use server
side prepared statements either the default needs to be not to use
cursors, or the sql string needs to be parsed looking for ';' and only
use cursors if no ';' is found.
