Re: merge command - GSoC progress

Dear Robert,

I have finished the tested edition of my code.

I think there are no redundant lines in this time's patch file.

And, I have tested the running of MERGE command with different situations. I
am sorry that I didn't create regression test files, because I am not sure
how to add new files in the git package. But, I have written web pages in
Postgres Wiki. I explain the details of my implementation and a set of
testing examples.

Please refer to the following pages if you are interested.

Thanks!

Yours Boxuan
