You can't use \0 in text types (text, varchar, char, etc); this is a
limitation of the server and the server/client protocol. The driver is
just catching it early so you don't see strange behaviour later.

In general, you don't need to terminate Java strings with \0 at all. If
you really do need to store a literal NUL, consider using a bytea column
and PreparedStatement.setBytes() instead.
