Some git related questions

Hi,

More than questions, I want to be sure I get it right.

So, since a few days, we have a mirror of the pgadmin3 git repo on
github. That's great. Anyone can fork it. I did
(http://github.com/gleu/pgadmin3) I'm working on my fork till then.

I have two new branches, ticket225 that takes care of the work I need to
do to make Luis's GSoC patch commitable, and ticket227 that I use as an
exercice for my git-fu.

Ticket 227 is a simple patch to handle the new columns Magnus added this
afternoon on the pg_stat_all_tables. Great feature, BTW. Anyway, here is
what I did:

git checkout -b ticket227 (from master on a clone of my github repo)
vim, make, tests, etc
git add pgadmin/schema/pgTable.cpp
git commit
git push origin ticket227 (which uploaded my new branch on github)

Now, when I'll need to commit it, I think I understand how to do this,
but I want to make sure before making any mistakes. Here is what I think
I should do:

from a clone of the pgadmin3 repo (not the github one, the one from
git.postgresql.org)

git remote add github git://github.com/gleu/pgadmin3.git
git fetch github
git checkout master
git merge ticket227

But, if I do this, I see my commit from ticket227 and I see another
commit, a merge commit. Is there a way to not have this merge commit? I
can probably use git rebase to squash them, but I was wondering if there
was something better).

Last question. How can I pull the new commits from the the github mirror
onto my github fork?

Thanks. And sorry if it is a bit out of topic.
