I need to bind a UUID parameter which may be null in a statement like "select * from test table where ? is null or ? = c_uuid".
Whatever approach I use, the driver rejects my request with "ERROR: could not determine data type of parameter $1".
[...]
But in the current implementation of the driver, the PreparedStatement.setNull(int, int, String) delegates to setNull(int, int) so that specifying the type name has no effect.
JDBC Driver bugs are off-topic for this list. They should be reported on the project's GitHub site's Issues List.
