Thinking of the 0002 patch, I'm also inclined to agree that this fixes
a bogus tab completion behavior for COPY command and can be
back-patched to v14. In v14, c273d9d8ce reworked the tab completion
for COPY command and supports the completion for the options of FORMAT
within a WITH clause so we cannot back-patch it to v13.

Torikoshi-san, could you please prepare the patch for other branches
too if you agree with this direction?
