Re: Naming conventions for column names

Hi,

It seems people worrying about failure of client side code after changes in
column names.

Melvin also mention that just change in one column was broken many things.

Sure. It make sense.
Definitely we can do this. Specially patch reviewers and committers need to
take care of this. (I am not ordering to anyone here, just putting my
thoughts)

It is correct. But then I think we can do below things:

1. Instead of pushing all changes at once , we can group them and push them
slowly in each major version release.
2. We need to decide weather we really need those changes in old versions?
3. Notify or highlight these changes in release notes because this can
break some existing tools and user code.
4. As Alvaro suggested, when developer working on any major code change, He
should give proper naming conventions to system catalog/view column names
in that area.

If It is impossible or not required to do this, then we can stop discussion
with 4th point made by Alvaro as conclusion of this discussion.

Please committers give their final view on this.
