Disclaimer: I don't do java stuff myself, all I know about this is from
reading the code.
First, there's a connection parameter stringtype=unspecified that
affects all setString calls on the connection. Second, there may be a
way to use setObject instead; setObject(1, str, Types.DISTINCT) looks
like it might work (or maybe Types.OTHER) - unless I'm completely
misreading the pgjdbc code, that should end up sending the right thing
to the server.
