-  * Planner improvements 
-  * Online server addition and removal 
-  * Triggers 
-  * Cross-node operation optimization 
-  * Configuration and opration utility 
+  * Postgres-XC already has sufficient feature. 
+    * Missing features are not seriously used in production. 
+  * Should concentrate on stabilization and bug fix. 
+  * Catching-up PostgreSQL may not be urgent issue. 
+  * Make community process more open. 
+  * Publishing simple benchmark is sufficient. Just concentrate on DBT-1, DBT-2 and pgbench. 

-## Upcoming Releases and Features
+To-do list below has a bunch of features. Most of them can be classified as: 

-Current plan of future releases and features are as follows: 
+  * Performance improvement, 
+  * Improve cluster configuration and operation, 
+  * High-availability. 

-### Release 1.2
+To-do list and priority is subject to realistic use case and resource. Further discussion/proposal and development effort are very very welcome. 

-Release 1.2 will include the following features. 
+## List of ToDos

-  * Merge with PostgreSQL 9.3.x. This may include the following new features. 
-    * Event Trigger 
-    * Materialized view 
-    * Updatable view 
-    * LATERAL 
-  * Also, release 1.2 will come with planner improvement. 
+### PG Merge

-Now beta release date is supposed at the end of December, 2013. 
+  * PostgreSQL 9.4 merge 
+    
+    * This is high priority because we want to stay in sync with PG.
+    

-### Beyond 1.2
+### Single Binary for Postgres-XC

-  * Coordinator and Datanode Integration 
-  * Planner improvement 
-  * Migrating GTM Proxy into coordinator/datanode backend 
-  * Foreign Data wrapper 
-  * Batch, statement pushdown 
-  * SSI and REPEATABLE READ 
+  * Coordinator/Datanode integration 
+    * When only one node is running as a cluster, planner should produce the same plan as current PostgreSQL. 
+    * Simplify cluster configuration/operation 
+    * This will improve read transaction by local cache at coordinator level. 
+  * GTM/GTM Proxy integration into user backend or postmaster. 
+
+### Performance Improvement
+
+  * Subquery optimisation 
+  * DML Planning 
+  * Executor refactoring to support binary mode 
+    * Needed for better support of JDBC 
+
+### Statics Collector
+
+  * Statistics (Maintain global statistics. Necessary for planning big queries as seen in DBT-3) 
+  * Query optimisation (statistics) 
+
+### More PG compliance
+
+  * SELECT FOR UPDATE 
+  * WHERE CURRENT OF 
+  * Long object support 
+
+### Partitioning
+
+  * Distribution column update 
+  * Alter table concurrently 
+  * Range and list distribution 
+
+### External data sources
+
+  * Database links 
+  * FDW 
+
+### Transaction
+
+  * SAVEPOINT 
+  * Global deadlock detection 
+
+### Administration
+
+  * pgxc_ctl improvement 
+  * Barrier improvement 
+    * Synchronize PREPARE in explicit 2PC if applicable. 
+
+### Constraints support
+
   * Global constraints 
+
+### Connectors
+
+  * CREATE TABLE AS in JDBC 
+
+### Other
+
+  * DBT-5 Analysis and running DBT-5 with Postgres-XC 
+  * Use of temporary object with implicit 2PC 
+  * General OID/CTID handling 
+  * General function handling 
+  * upgrade utility for upgrading a PG standalone database to PG XC cluster 
+  * Pooler enhancements / refactoring 
+
+### Known Bugs
+
+  * Fix the bug #311 (fail to commit in plpgsql) 
+  * Fix the bug #427, some statment stack with EXECUTE DIRECT
