> Jdbc v2 driver has hardcoded values for meta attibutes : 
> COLUMN_NAME = _KEY 
> KEY_SEQ = 1
> PK_NAME = _KEY
> But this values should be different for different tables.
> how to reproduce: 
> 1) connect to the cluser using jdbcv2 driver
> 2) CREATE TABLE TAB (ID LONG, SEC_ID LONG, VAL LONG, PRIMARY KEY(ID, SEC_ID))
> 3) check result of connection.getMetadata().getPrimaryKeys()
