Thanks for your reviewing, and sorry for my late response.

I definitely agree with your solution. The reason why my original patch
had separate code path for function and collation was they took
additional elements (such as argument-list of function) to check
duplicate names. So, I think it is a wise idea to invoke the common
code after name duplication checks.
