@yahonda After passing Travis CI build, should I open a PR that backporting this commit to nextval branch?

[koic]

Or is backporting unnecessary? There is a solution such as rebase master on nextval branch.

(About the function/branch of the future, the phrase "backporting" was strange.)

Thanks for your work and good question.

The short answer is no. Since nextval is a kind of topic branch (feature branch) which will be merged to master at some future, unlike other release18 branches.

In the meantime, I'll merge master branches into nextval branch periodically.

I have merged master branch into nextval. c29bf31 . Going foward merge operation for nextval branch will be done without issues/pull requests.

Thanks for your reply. I understood the policy of development on nextval branch.
