Hi,
 
I finished the MERGE on inheritance tables. Now comes the merge_v201
 
 
Thanks

Hi,
 
Here comes the new patch for MERGE command. It has the following features:
 
1. It is based on Heikki's merge_v102-cleanedup.patch. So, it is (hopefully) clean -- no meaningless white spaces and no overlong clause.
 
2. The "replaced" mark in MERGE query and plan structures are removed. In rewriter, the actions replaced by INSTEAD rules will be changed into DO NOTHING actions.
 
3. _outDeleteStmt() is removed from code.
 
4. EXPLAIN MERGE is improved much. You can see the new examples at https://wiki.postgresql.org/wiki/MergeTestExamples#Explain_Merge
 
5. The subplan/sublinks are supported in merge actions now. Try the examples at https://wiki.postgresql.org/wiki/MergeTestExamples#Subplan.2Fsublinks_in_action
 
6. Updated merge.sql and merge.out for regress
 
7. The inheritance is still NOT supported yet.
 
Thanks
 
Regards
 
Yours Boxuan
