Description:
DatabaseMetaData#getPrimaryKeys should be ordered by COLUMN_NAME.

I see the following order.

PrimaryKey(
    tableCat=performance_schema,
    tableSchem=null,
    tableName=session_account_connect_attrs,
    columnName=PROCESSLIST_ID,
    keySeq=1,
    pkName=PRIMARY
)

PrimaryKey(
    tableCat=performance_schema,
    tableSchem=null,
    tableName=session_account_connect_attrs,
    columnName=ATTR_NAME,
    keySeq=2,
    pkName=PRIMARY
)

How to repeat:
Invoke and see.
