KunlunBase is a distributed relational database management system(RDBMS) with complete NewSQL capabilities and robust transaction ACID guarantees and is compatible with standard SQL. Applications which used PostgreSQL or MySQL can work with KunlunBase as-is without any code change or rebuild because KunlunBase supports both PostgreSQL and MySQL connection protocols and DML SQL grammars. MySQL DBAs can quickly work on a KunlunBase cluster because we use MySQL as storage nodes of KunlunBase. KunlunBase can elastically scale out as needed, and guarantees transaction ACID under error conditions, and KunlunBase fully passes TPC-C, TPC-H and TPC-DS test suites, so it not only support OLTP workloads but also OLAP workloads. Application developers can use KunlunBase to build IT systems that handles terabytes of data, without any effort on their part to implement data sharding, distributed transaction processing, distributed query processing, crash safety, high availability, strong consistency, horizontal scalability. All these powerful features are provided by KunlunBase. KunlunBase supports powerful and user friendly cluster management, monitor and provision features, can be readily used as DBaaS.

Assign attrelid for result columns from prepared stmt execution #744

Issue migrated from trac ticket # 742

component: computing nodes | priority: major

Currently the Form_pg_attribute::attrelid isn't set(it's 0) for result columns from prepared stmt execution, causing kunlun_client_test's test_prepare_field_result to fail because no table name is returned.

And the Form_pg_attribute::attname stores column alias name rather than column real name, and without the attrelid we won't be able to find the column's real name from metadata.
