From "emacs -Q":
1. Create a new buffer and write something into it.
2. Type "C-x C-s" and save the buffer as "test.txt".
3. Now Type "C-x C-w" and save another copy as "test.sql".
The mayor mode chosen for the "test.sql" buffer is "SQL", whereas the
one chosen when I kill all buffers and visit the "test.sql" file is
"SQL[ANSI]". I expected that the chosen mode was the same in both
cases.

The issue you are reporting is specific to sql-mode.
The [] piece is added by sql-highlight-product, which sql-mode runs via
hack-local-variables-hook. Changing a buffer's filename changes the
major-mode (if change-major-mode-with-file-name is non-nil), but does
not re-hack the local variables.

I guess it probably should, since any specified file local variables get
clobbered by the mode change.

As mentioned in some earlier post (several months ago), I think that
normal-mode should run hack-local-variables.

It already does (and always has)?
set-auto-mode is being used here though, not normal-mode.

So I guess we shouldn't use set-auto-mode here.

normal-mode first switches to fundamental-mode, then changes to the
right mode, then turns font-lock off and on. Is that necessary here?
Also it does not have a "keep-mode-if-same" argument.
It seems simpler to me for set-visited-file-name just to
hack-local-variables.

For 24.1, yes. But in general we'd want to restructure the code a bit
to make it harder to avoid running hack-local-variables-hook (or maybe
provide a new hook to replace it, which is guaranteed to run after
changing a major-mode).
