Yes. Being able to do this is useful for several reasons. For example,
it's useful to be able to create a new, equivalent index before
dropping the original when the original is bloated. (You could use
REINDEX instead, but that has some disadvantages that you might want
to avoid.)

Questions like this are better suited to the pgsql-general list.
